In Genesis 2:9, Christ was typified by the tree of life. The tree of life, belonging to the vegetable life, is good for producing and generating, but has no blood for redeeming. At the time of Genesis 2, man was not yet involved with sin and thus had no need for redemption. However, in Genesis 3 man fell. Immediately after man’s fall, God came in to deal with that fall by slaying sacrificial lambs to redeem Adam and Eve and to make coats of skins to cover their nakedness (Gen. 3:21). Thus, the vegetable life itself is no longer adequate for fallen man; there is the need of the animal life.
