22 Then the Lord God said, “Behold, the man has become like one of Us, to know good and evil. And now, lest he put out his hand and take also of the tree of life, and eat, and live forever”—23 therefore the Lord God sent him out of the garden of Eden to till the ground from which he was taken. (Genesis 3:22–23, NKJV)
God understands the heights of goodness, and the depths of evil. Sin’s intrusion into the lives of Adam and Eve impacted their knowledge of good and evil. Indeed, before their sin, they had experienced good things from the hand of God. Before their sin, they had trusted God’s warning that evil would cause them to die. But, with their sin, they experienced evil, along with its death. Yet, God’s purpose of man and woman’s fellowship with Him would not be defeated by evil; the promised seed of woman would crush the serpent’s head. This was accomplished in Christ (Genesis 3:15; Galatians 4:4-7; 1 John 3:8). Eternal life is incompatible with evil. Therefore, they were sent out of the garden, and denied access to the tree of life (Genesis 3:24). Could they have understood evil without experiencing it? Yes, just as surely as a child can know the danger of fire from his parents’ warning, without putting his hand into the flame. You do not have to sin to perceive the pain and sorrow it causes. Instead, trust God’s warning against sin, and His offer of eternal life. Evil brings death. Eternal life is in His Son (1 John 5:11).
