This is not quite as obvious as it might seem at first. But, after all, God did not simply destroy Adam on the spot, as he might have; he does say, “in the day that you eat from it you will surely die” (Gen 2:17), and “the day” might very well mean the very day on which the sin was committed. But that is not what happens; we will explore why a bit farther down. Still, Adam will eventually grow old and die, and the assurance of death comes mainly from deprivation of the Tree of Life, which God achieves by expelling him from the Garden. Moreover, the manner of death—returning to the elements of which Adam was made, after which he was named—fits perfectly, “for dust thou art, and unto dust shalt thou return.”
