If people claim to be sent by God, how would you know whether they really were? Scripture teaches that miracles function as God’s public endorsement—His witness that a messenger truly is from Him. And nowhere is that clearer than in the miracles at Jesus’ death, when the Father surrounded the crucifixion with signs that testified that Christ is the One He sent.

Miracles authenticate those truly sent by God
The Greek word apostle means “one who is sent.” The apostles claimed to be sent by God—and the Lord confirmed that claim with signs. Scripture is explicit:
2 Corinthians 12:12 — “The signs of a true apostle were performed among you…with signs and wonders and mighty works.”
Hebrews 2:4 — “God also bore witness by signs and wonders and various miracles and by gifts of the Holy Spirit…”
Miracles are not religious entertainment. They are God’s testimony.
Now consider this: Hebrews 3:1 calls Jesus “the apostle.” Jesus is the ultimate One sent from the Father. And if God authenticated the lesser apostles with signs, how much more would He testify to the true and greater Apostle—His own Son? As we come to Luke 23 and stand at the foot of the cross, we see the Father doing exactly that.
The Father surrounded the cross with supernatural testimony
Luke records miracles at the crucifixion that were impossible to miss:
Darkness over the land
The sun’s light failing
The temple curtain tearing
The earthquake
Tombs opening and saints raising from the dead
God the Father did not leave the world to wonder whether this was just another execution. He surrounded the death of His Son with signs that revealed the identity of the One being crucified.
Luke begins with the first miracle:
“It was now about the sixth hour… and there was darkness over the whole land until the ninth hour…” (Luke 23:44)
From noon until three in the afternoon—the brightest part of the day—darkness covered the land. This was not weather. It was a sign.
Lesson 1: The darkness reveals the evil of Jesus’ death
Scripture repeatedly uses light and darkness as moral and spiritual metaphors—good and evil, righteousness and wickedness. Even earlier in Luke, Jesus rebuked the leaders who came to arrest Him at night:
“This is your hour, and the power of darkness.” (Luke 22:53)
Their actions were physically done at night, but Jesus exposed the spiritual reality behind them: darkness—evil—was at work. Now at the crucifixion, what had been spiritual becomes physical. Literal darkness covers the land to display the evil of what is happening: the sinless Son of God is being murdered.
Lesson 2: The darkness also reveals God’s judgment
Darkness in Scripture doesn’t only picture evil; it also often accompanies judgment. So the question is: on whom is judgment falling?
Not on the criminals—though they deserved it.
Not on the mocking crowd—though they deserved it.
Not on the Romans—though they deserved it.
Instead, judgment falls on Jesus. The innocent One is treated as guilty. The One who knew no sin is made sin for us. This is substitutionary atonement—our sin imputed to Christ, His righteousness imputed to us:
“For our sake He made Him to be sin who knew no sin, so that in Him we might become the righteousness of God.” (2 Corinthians 5:21)
The darkness is God’s testimony: sin is being judged—and Christ is bearing that judgment in the place of His people.
Lesson 3: The failing light points to the Light of the World being extinguished
Luke adds another detail:
“…while the sun’s light failed…” (Luke 23:45)
Luke already told us it was dark. So why add that the light “failed”? Because Luke is not describing an ordinary dimming. He is describing a sign—language that echoes who Jesus is. Jesus is the Light of the World:
“I am the light of the world…” (John 8:12)
So when Luke says “the light failed,” it’s hard not to hear the theological echo: the Light of the World is being extinguished. But this does not mean Jesus failed.
“No one takes My life from Me… I lay it down of My own accord.” (John 10:18)
The light did not “fail” because Christ was overpowered. The light “failed” because Christ willingly stepped into the darkness we deserved. He entered judgment to deliver His people from judgment.
Jesus died in control
Luke records Jesus’ final words:
“Father, into Your hands I commit My spirit!” (Luke 23:46)
Crucifixion made speaking agonizing. Yet Luke tells us Jesus cried out with a loud voice. This reveals something crucial: He was not a helpless victim. He died when He chose to lay down His life.
The Father pressed Jesus’ innocence on everyone watching
Luke then records the centurion’s response:
“Certainly this man was innocent!” (Luke 23:47)
All through Luke 23, Jesus’ innocence is repeated. It is as though the Father insisted the world hear it while His Son was being killed: Jesus is innocent.
Lesson 4: The cross should produce repentance
Luke says the crowds went home “beating their breasts” (Luke 23:48). That phrase matters because Luke uses it elsewhere: The tax collector “beat his breast” and cried, “God, be merciful to me, a sinner!” (Luke 18:13). In Luke, beating the breast is not casual emotion. It is brokenness over sin. It is repentance.
God did not surround the death of His Son with signs so people would walk away impressed. He surrounded the cross with signs so people would walk away convicted. The darkness tells us sin is real and judgment is real. The cross tells us that grace is real and that forgiveness is available.
The question is not whether the signs were powerful. The question is what we will do with the One they point to. Will we respond like the hardened scoffer—or like the tax collector, the convicted crowd, and the centurion—owning our sin, confessing Christ, and pleading for mercy?
If we come to Jesus in faith—confessing our sin and trusting His substitution—we will never have to fear the darkness of judgment, because the Light of the world stepped into it for us, so we could walk in the light of life.
