So he drove out the man; and he placed at the east of the garden of Eden Cherubim, and a flaming sword which turned every way…
Observe, the tree of life was not cut down; nor was it withdrawn from the trees of the field — no, the tabernacle of God was left with men upon the earth. Well was the way watched until the time should come for approach: strait is the gate and narrow is the way that leadeth unto life, yet men may travel now up to the blessed tree and take the fruit of immortality! God has never taught us to set little store by life. He has always watched it and guarded it as with hosts of armed angels. It is not to be wantonly plucked. It is God's choice gift. He has, too, alway kept the line very distinct between Himself and His creatures "the man is become as one of Us, to know good and evil"; not really as "one of Us," but imaginatively so; he thinks he now knows all that there is to be known, but this imagination must be corrected by the imposition of high discipline: he thinks he has discovered the sham and failure of things and found out the scheme of God; he must be undeceived; throw a skin upon his back, drive him out of the garden, keep the tree of life, and let him learn by long and bitter experience that there is no short road to dominion and immortality.
(J. Parker, D. D.).
