Power Through Constructive Thinking - The Garden of Allah - Part II

Emmet Fox studies Isaiah 25 to find spiritual truths which when practiced can change your conscious and subconscious mind to improve your mental and moral state.  That is to say that  a healthier mind will develope, evil will be crowded out and good grows and problems of all kinds are decreased or eliminated all together.  I still do not understand why the author calls the chapter, the Garden of Allah.
