The barrier of Cherubim which blocked Adam's entrance to the Garden after the Lord thrust him out, reminds us of what cast mankind out of the Garden to begin with. The choice to eat of the knowledge of good and evil is the culprit. The reason Cherubim remind us of this is due to the fact that Cherubim were first mentioned in the Bible as blocking Adam's return to the Garden of Eden after being cast out. The first mention of a thing in the Bible sets the pace for its meaning throughout the remainder of the Bible. Today, as believers, we remain with a choice that is identical to Adam's.
Believers have two sources from which to draw strength.
There is the flesh, or the Spirit of God, God's Life. The flesh works on the basis of the amount of knowledge of good and evil which one possesses. Fleshly folks are convinced they have no need to go to a higher power for assistance in life. Such folks do not seek foreign empowerment. They merely wish to increase their storehouses of the knowledge of good and evil.
