The Theology of the Ordinary: How Jesus Reveals God's Kingdom Through Mustard Seeds

In this episode of The Reformed Brotherhood, Jesse Schwamb explores Jesus' parable of the mustard seed from Matthew 13. The seemingly insignificant mustard seed grows into a mighty tree, providing a profound metaphor for God's kingdom—beginning in humble, ordinary ways yet expanding to glorious fulfillment. Jesse unpacks how this parable challenges our expectations of power and glory, revealing that God intentionally works through what appears small and insignificant to manifest His mighty power. This episode offers a meditation on God's kingdom, which operates contrary to human expectations, growing unstoppably between Christ's first and second comings despite opposition, and ultimately providing shelter for all nations.

Key Takeaways

• The kingdom of God begins with something small and seemingly insignificant (a mustard seed) yet grows to become greater than all garden plants
• Jesus deliberately uses ordinary, humble elements to describe God's kingdom, contrasting with human expectations of power and glory
• The theology of the cross consistently looks to normal, ordinary means rather than what people perceive as great and powerful
• There is significant growth of God's kingdom between Christ's first advent and His eventual return
• God's kingdom cannot be stopped by opposition; attempts to destroy it actually facilitate its growth
• Biblical meditation on Jesus' parables is essential for deeper understanding and application
• The parable connects to Old Testament imagery (particularly in Daniel and Ezekiel) where trees represent kingdoms

The Theology of Ordinary Means

The parable of the mustard seed demonstrates what Jesse refers to as "the theology of the cross" versus "the theology of glory." God consistently chooses to work through what appears weak, small, and insignificant rather than through impressive displays of worldly power. As Jesse explains, "The theology of Cross is always looking to these normal, ordinary insignificant things. It's God's stacking the deck against himself to show his great power that he works not... in the circumstance of what people perceive to be great and powerful, but the exact opposite." This approach reveals God's sovereignty—He needs no human advantage, political power, or military might to accomplish His purposes. The kingdom that began with Jesus' seemingly humble first advent will culminate in His glorious return, showing that God's power is made perfect in weakness.

The Unstoppable Growth of God's Kingdom

One of the most encouraging aspects of this parable is how it portrays the inevitability of the kingdom's growth. Just as a mustard seed inevitably grows into a tree according to its nature, God's kingdom advances despite opposition. Jesse notes how throughout history, attempts to destroy Christianity have always failed: "History is replete with those... who have tried in their own way to silence God, to destroy the scriptures or to somehow eradicate Christianity. And of course, history will be filled up with all of their failures." Even the martyrdom of Stephen in the early church, which seemed like a defeat, actually caused the gospel to spread beyond Jerusalem as believers were scattered. This illustrates Jesus' promise that "the gates of hell will not prevail against his church" (Matthew 16:18). The kingdom continues to grow by God's power until its final consummation when Christ returns.

the theology of Cross is always looking to these. Normal, ordinary insignificant things. It's, God's stacking the deck against himself to show his great power that he works not with great po, not in the circumstance of what people perceive us to be. Great and powerful, but the exact opposite.

Welcome to episode 467 of The Reformed Brotherhood. I'm Jesse, and this is the podcast with ears to hear. Hey, brothers and sisters. Well, we're back at it again.

[00:00:48] Exploring the Kingdom of God Through Parables

On this episode, we're talking about seeds and leave. In what other ways would Jesus describe the kingdom of God? And we're gonna get to all of that, but in a slightly different format.

Something special for everybody on this episode. It may have noticed that. Right at the top. Tony is missing, but fear not. He's still here. We're doing something different on this episode and that is we're gonna speak about the kingdom of God as Jesus describes it in parable form with the mustard seed and the leave.

And so what we decided to do is I'm gonna give a quick little primer, my thoughts, my observations. On the mustard soup parable, and then Tony will be right behind me to talk about the leaven. And then in the next episode, we're coming together and we're gonna see how all of our different explanations kind of come, came together and coalesced around single themes.

So this is a fun little game where you're gonna hear from. You're gonna hear from Tony, and we're gonna see how all of this comes together in the end, because neither of us is having the conversation in real time, but I'm sure that we're gonna have a lot of the similar things to say and it'll be a fun little game of seeing how all of this comes together.

So if you wanna play along. And you definitely should come hang out with us in Matthew chapter 13.

[00:02:04] The Mustard Seed Parable

So we've gone through a couple parables already and the beauty of looking at these parables, of course, one of the many beauties, I guess I should say, is that we're getting some direct teaching from Jesus, which is always great, and we're getting it directly about the Kingdom of God.

The God perspective on salvation. Clear, concise, in parable form. And so we found ourselves looking at fields, looking at planting, looking at weeds, looking at tears, looking at wheats. And now after all of that, we're coming back. To in some ways, at least for me, a familiar form. And that is we're back to seeds again.

And this time it's a particular type of seed. It's the mustard seed, and Tony's gonna handle something new, a total change in direction, a totally different comparison. He's gonna get into lemon and bread making and all that kinda good stuff. But in either case, what we're finding is Jesus is specifically coming to us once again.

With these finely tuned stories to help explain to us the kingdom of God. And of course, like this is clear because in all of Jesus' teaching, the kingdom of God holds this like high and lifted up this prominent position. It gets hegemony in all the other topics. And as he goes about his earthly ministry, wherever gospel you look, you're gonna find that he's proclaiming his coming to earth and that this coming meant that the kingdom of God was at hand.

Now, I can only imagine, and you ought to as well, that if you were in that time, if you were listening to Jesus. What an incredible thing that would be that you're trying to understand and really discern what the he means about this kingdom of God. And perhaps like you, I would have my own perceptions of what that was, and if he's inaugurating it, I'm waiting for that thing to happen.

And a kingdom is a powerful representation of ownership. Power in hierarchy in a place that's clearly manifested. And so as Jesus is in the midst of all these hears, these disciples that are gathering around the throngs of people that are trying to understand what he has to say. If he's coming and saying, I am here to inaugurate the kingdom of God, then my first question would be.

Where is it? Tell us what it's gonna look like. Show me what you mean when you say that the kingdom of God is here, that you're ushering it in. And so how strange and unusual then for Jesus to say something like the kingdom of God is like a mustard seed, or the kingdom of God is like lemon in bread. So it seems altogether fitting that Jesus would want to and would have to explain what exactly he means.

It's a little bit though mysterious that he uses these elements. To bring about that kind of explanation. I find that endlessly fascinating.

[00:04:32] Meditation on Jesus' Teachings

Speaking of which, I think one of the reasons why Tony and I are discovering that we're loving these parables so much is that it forces us to do something that sometimes is Modern Christians we're honestly just not that good at it, not skilled and often not practiced because our lives are filled with many things.

And we prefer not to do this, and that is to actually meditate on what he's saying, to actually like turn it over in our minds to think about it. Like personally, practically, seriously, and earnestly to understand how the truth of God's words should look in life. And it just dawned on me this week that really the parable forces us into that rubric, whether we want to or not, because the whole purpose is to take what he's saying and to dwell on it to such degree that we receive something of the promises that are therein.

By chewing on them. And it's just too easy to read the scriptures, of course, and to take with you as you pass by those words, something of a little bit of the knowledge that's contained within something about the phraseology or about the facts of it. But really what God's after here is this idea that we would spend time meditating on the words of Jesus, so that we might truly understand what he means by the kingdom of God.

And then we might take that kingdom into our own realm, as it were, into our own sphere of influence to manifest it. And to worship him through it and to be obedient in it. Be not because of works on the righteousness, of course, but because we already have been saved by a great savior for this kingdom.

And now we know something about what it's actually like by way of these beautiful metaphors. And of course, like the metaphors, even if they're straightforward. As we're about to find in this one, still force us into them to really say, well, what? What does it mean? We're gonna talk about seeds and mustard plants, and where else we find trees in the scriptures.

Without meditation, we lose so much of this without meditation. Truths are maybe devoured, but they're never digested. I like what the great Puritan Watson wrote. He said, it's better to meditate on one sermon than to hear. Five sermons. Many complain that they do not profit from sermons. This may be the chief reason, because they do not chew the cud.

They do not meditate on what they have heard. And I think one of the great goals that Tony have in this series is that even as we're thinking about this before we have conversation with each other and present it all to you, that we really wanna spend time truly meditating on it, thinking practically, deeply for a long period of time.

On what is being said here, what Jesus means by it, that it is for us, that it is a gift that he gives to us. And so I really totally resonate with what Watson is saying here, that when a Christian enters into meditation through the scriptures, that they receive healing, they receive power from God, that receive insights and wisdom, that receive his comforts, that receive his direction for life, and that all of that is, or most of that.

Rather is lost if we move too quickly by it. We tend to gather a lot of knowledge, but maybe not a lot of the wisdom that's contained in there. So even if this sounds simple, this little parable that's before us, it's just a couple of verses. Loved ones that there is so much in it for us to understand and to chew on.

I don't think we can expect to get all the understanding in one go and that's okay. We keep coming back to it. Certainly. I'm not gonna cover it all here. This is definitely not going to be, though. You might expect it, the definitive episode. On the parable of the mustard seed in the lemon. It can't be really, and that's because there's just so much for us to understand here and to receive from God.

So that is the longest intro ever. So let me cut it there and let's just go right to the scripture, which of course is the best part of this podcast. Always. So this is Matthew chapter 13, beginning in verse 31, just a couple of verses. Jesus put another parable before them saying The kingdom of heaven is like a grain of mustard seed than a man took and sowed in his field.

It is the smallest of all seeds, but when it has grown, it is larger than all the garden plants and becomes a tree. So that the birds of the air come and make nests in its branches. Lovely. Right. It's wild because it's such quick language there. It's so brief and already I wanted to go further, but I would be into Tony's verses, which he's gonna hit with us in just a second for.

But it's really compact statement of just a couple of things. One, can we just agree that I love the way that this particular little passage begins? It just starts by saying, Jesus put another parable before them. What beautiful language that he's really throwing before his disciples placing for them to evaluate again, to meditate on these beautiful words of his that express what the kingdom of heaven is like.

It's of course, well within God's purview. To not have given us any kind of direct revelation here, or direct expression or even metaphorical or comparative expression of his kingdom. How kind that he does this. And then I think there is something for us to study in this, again, to chew the cut, as Watson would say, on what it means for us to think about heaven as this grain of mustard seed and that a man took it.

And he sewed it in his field. It's very small, yet it grew larger than all of the other garden plants that would probably be in that field. It became a tree, and then as a result of that, the birds of the air come and make its nest in its branches. So you can see that there's all this interesting, logical pro progression throughout this passage.

And we're talking about really just two verses, really, just that many sentences. It's really exceptional thing, you know.

[00:09:52] The Growth of God's Kingdom

I find it interesting that this illustration progresses this idea of the kingdom of God between its inauguration and consummation. There's something built in there, and like I said, I think it's realistic to assume that so many who are hearing these words we're really, truly trying to understand.

Where was this kingdom, Jesus, that you're bringing in as the Son of David, show us this kingdom and its power and my own expectation. I still don't mean to put this on. Those who would've been there would've been that this kingdom would've come in power. I was waiting for it to be manifested with this sense that it would be very clear that Jesus was in.

That all things, all realities both here and now in spiritual principalities will be clearly under his foot. We were looking for, we want to see the serpent crusher, the head crusher the better. David, the one that comes inlays Goliath Finally. Where is that pump and where is that power? And interestingly, Jesus says, no, actually, it's more like a mustard seed.

And of course, I mean, you don't need to know much about seeds, but if you haven't looked up a mustard seed at this point, you definitely should because it's very tiny. That's obviously implied from the text, but it is very tiny, like crazy tiny, like almost so tiny that when I look at a mustard seed, whether you're like, you're looking at your.

From your like spice rack or you go and Google one, it almost seems inconceivable that any size plant could come forth from that very, very tiny seed. It's so mundane and insignificant that the idea that Jesus would say, this is what this glorious kingdom of God is like, is almost mind boggling. Like even now it's mind boggling.

And if it's not, it's because you have not looked at a mustard seed. Go check that bad boy out. It's so small. And so of course like Mustard would've been a common agricultural product that grew quite prolifically in that particular area. You know, the variety of mustard seed growth in PA in Palestine is probably similar, I imagine to like maybe most of like the northern hemisphere.

There's various. Kind of varieties, of course of mustard seed. What I've learned since trying to chew on this text, and they grow in very all kinds of varieties, but this idea that this small seed can become something that you put in your garden, that grows to such a great extent that it dwarfs all of the other things.

And of course it starts. In the most, I don't wanna say humble, that's like, that's almost too much. The most insignificant way is incredible. So the fact that, again, we have, I think in this something that Tony and I have come back to quite often, and that is the difference between the theology of glory and the theology of the cross.

That the theology of Cross is always looking to these. Normal, ordinary means these insignificant things. It's, as we've said before, God's stacking the deck constantly against himself to show his great power that he works not with great po, not in the circumstance of what people perceive us to be. Great and powerful, but the exact opposite.

And I think not just as the Bible communicates, not just to display his mighty power, but also to shore forth his great glory that he needs no other thing. And because he needs no other thing, he doesn't need things to go right for him. He doesn't need the right political leaders to be involved. He does not need armies.

He does not need kingdoms. He inaugurates his own. And his own is so great and so powerful that it became, it can begin in the most insignificant way because the power is not itself in the planting of that thing, but in the thing that makes it grow. And so here we have this clean and clear delineation when it comes to trees that God, again, is doing the planting and this tree is gonna grow to such a great extent that dwarfs all the others besides it.

And that not just that, it becomes a resting place. It becomes a living place, a place that provides shelter. And so. It's, that is a common theme that we find, like throughout all of the scriptures. In fact, I, I often think like God has a thing for, for a couple of different items. One is tense. God loves tense, loves sojourning jam.

Then the third would be trees. I mean, look throughout the scripture and see where God is either using trees directly or using, this becomes like a grand metaphor explanation for so many of other great spiritual and theological principles. That's whether we go back all the way to the beginning in the guided and we see the tree of good evil, tree of knowledge of good and evil.

Tree of Life rather. In addition to that, then we have all these other references, especially in the Old Testament, but I mean, whether it's Abraham and he's souring and he's, we're getting way points by way of trees, for instance, or whether we are in the New Testament and we're talking about fig trees.

There are all these references to trees. They're embedded and impounded in the lifeblood of God's work and the story that he's telling, the grand narrative of salvation of his people.

[00:14:35] Historical and Biblical Context

And nowhere is this, I'd say more true than in places in the Old Testament, especially when we're speaking about like the book of Daniel Daniel, chapter four.

So for instance, if you go back there, you're gonna find that this description here in some ways. Has it. I think parallel is probably not strong enough a word. There's like this direct connection between what God talks about and through the power of the Holy Spirit in the book of Daniel and what he Jesus' son is saying here.

And in that book we see the descriptions harkening back to King Nebuchadnezzar, Babylon. He had a dream about a tree that had grown so large that the birds of the air rested in it. However, that tree was chopped down an instant. And Daniel's interpretation revealed that all the kingdoms a man will collapse, even this mighty nebuchadnezzar's kingdom.

But God's kingdom that Jesus draws a parallel here to here is different. Although the inauguration of his kingdom was unimpressive, it's going to grow until it reaches final glorious form, until the birds of the heavens common nest and its branches, which by the way, is basically exactly out of Ezekiel 36, 31, chapter six.

All the birds of the heavens made their nest in its bows under its branches. All the beasts of the field gave birth to the young and under its shadow, lived all the great nations. So lest is hearers miss this message here. You know, Jesus is saying very clearly, listen, there is growth of God's kingdom.

Between his first and second advents and in them, Jesus showing the manner in which he's ushering in this kingdom of God and need not sow any doubts concerning the power and legitimacy of his Messianic office and of this kingdom that he's bringing in. The humble inauguration was not a mistake. You know, this is planned by God and it is for his great purpose.

It shows. His great power, his love for his people, and the ordinary way in which he brings about all of these things. And we can see this in fact, some. One of the great blessings is that we sit in this place where we can interrogate, examine, have these parables read us, and we see that since Jesus uttered these parables, the mustard seed has in fact taken root and blossomed, you know?

Those who oppose Jesus and his followers after his ascension tried to squelch this infant church to chop down this tree. I love, you've heard me say before, loved ones. I love this description of job that we get from the scriptures, that even in our, let's say, the most miserable times, even when it seems like all hope has been cut off from us.

Even if it seems though it's never the case, even if it seems that we've been forgotten or forsaken, the scripture tells us of job. There's hope for job, like a cut down tree. There again, we have a tree and this, this idea that even though it was removed, it, new life springs forth from it again. New unassuming life, the kind of life that can only come from the creator, the one who restores all things, redeems, all things, loves his children, and for whom.

We find the exact truth manifested in from Romans 8 28, that for those who love God and are called according to his purpose, all things, all things, all things work for good. And so this infant church, while in its time it was trying to be. There was so many attempts to crush it, to destroy it, that it went far beyond Jerusalem.

All the attempts to do this were exactly futile. In fact, the more that God's enemies came both in the present day and in the previous day, the more they come where their AEs and try to chop at this tree, the more the tree grows. You know, a really wild example of this in the first century is the martyrdom of of Stephen, which I think is illustrative to this end because it precipitated a dispersion that carried the gospel beyond Jerusalem, into Judea, into Samaria, and to the ends of the earth, literally.

That's Acts eight. You know, the history of the church is truly the fulfillment of Jesus' promise right here in this text that not even the gates of hell would prevail against his church. That's from Matthew 1618, and I know I've said before, but man, does it bear repeating. That gates don't attack anybody.

Gates don't go out to battle. It's so for the Christian here, for what Jesus is saying, it's not that we have to worry that the gates of hell are coming after us, but that the normative position of the church is to grow in such a powerful and unassuming and mysterious way that even these gates, which will try to defend against the light, will not overcome it.

And so because of that, we find that. It now houses the birds of heaven, that it feeds the nations that is lifeblood and it provides fruit for all who are there? The kingdom that Jesus inaugurated awaits his return for its full and final consummation. And so in the interim, we walk by faith and not by sight.

We're citizens of that kingdom and we know it cannot be shaken. We know it's growing. You know, this is one of the things that I find incredible. I think you could have chosen. Any number of course of metaphors to explain what God's kingdom is like, and sometimes we choose our own and that's fun. We're trying to explain it in a particular way or maybe to express some kind of nuance of that kingdom.

But my bet is that we would not use the words that Jesus has given us here if it were left to us to try to explain it without any kind of great insight. And again, the reason why is because this is too humble. It's too unassuming. It doesn't seem like it contains within enough power, but that's because we have in this, again, this super intending will of God that he's so great, so majestic, that his thoughts are so incredibly deep that even what we have to do here is let our consciousness and reason bow down to who God is and to what he says his kingdom is like, because he always.

Brings it forth in every generation. He always brings it forth and it cannot be stopped. And of course, history is replete with those both individual leaders and cultures, movements and political heroes who have tried in their own way to silence God, to destroy the scriptures or to somehow eradicate Christianity.

And of course, history will be filled up with all of their failures because this unassuming seed, which God plants. Continues to grow by his power, his volition, his sustenance, until it takes over all things. And in that final consummation, it absolutely will loved ones. And so we find, I think so much encouragement in that when Christ returns to consummate the kingdom of God, no one will be able to deny its glory then.

And while many of us now where we look for that glory, we obtain that glory by faith and not by sight. And in the same way here that Jesus challenges us to say, look, this is how it works. And wow, do I wanna speak so much about the 11, but I've gotta save that for Tony. You know, the one who took on flesh and was born in a humble state will return in splendor and judgment to consummate this kingdom.

And so in some ways this is a warning. That what started as this humble means of Jesus in the first advent coming speaking peace to his people that will will ultimately be bookended with this kind of final judgment that reflects his full unvarnished glory. And then finally. Finally the dwelling place of God will be with man.

And in that way, the birds of heaven will nest in this tree, in this lovely coming together of a new heaven and a new earth of God with his people and us finally having that beautific vision of Jesus. So there's so much here. I think that's. We can spend a little bit of time chewing on, even if we just mull over in our mind, what does it mean again?

That this kingdom of heaven is like, like a grain of a mustard seed, that it gets sewn. That's the small must of seeds, but that when it's grown, it's larger than all the garden plants, and then it becomes a tree. And because it is a tree and is this great and glorious tree, all the birds of the air come and make its nests and its branches.

What are the birds? What are the, what are the nests? What are these branches? And of course, I think. There's so much there for all of us to really consider as we continue to ponder what it means for us to really follow the Lord Jesus Christ closely. So that is your little quick. Conversation about the mustard seed and the leaven.
