Sin breaks it down:
The man and his wife were both naked, and they felt no shame. – Genesis 2:25
Have you ever noticed how a little child can run naked through a room full of strangers without embarrassment? He is not aware of his nakedness, just as Adam and Eve were not embarrassed in their innocence. But after Adam and Eve sinned, shame and awkwardness followed, creating barriers between themselves and God. We often experience these same barriers in marriage. Ideally a husband and wife have no barriers, feeling no embarrassment in exposing themselves to each other or to God. But, like Adam and Eve (3:7), we put on fig leaves (barriers) because we have areas we don’t want our spouse, or God, to know about. Then we hide, just as Adam and Eve hid from God. In marriage, lack of spiritual, emotional, and intellectual intimacy usually precedes a breakdown of physical intimacy. In the same way, when we fail to expose our secret thoughts to God, we break our lines of communication with him.
(For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh. – Genesis 2:24. God gave marriage as a gift to Adam and Eve. They were created perfect for each other. Marriage was not just for convenience, nor was it brought about by any culture. It was instituted by God and has three basic aspects: (1) the man leaves his parents and, in a public act, promises himself to his wife; (2) the man and woman are joined together by taking responsibility for each other’s welfare and by loving the partner above all others; (3) the two become one flesh in the intimacy and commitment of sexual union that is reserved for marriage. Strong marriages include all three of these aspects.)
(Now the serpent was more crafty than any of the wild animals the LORD God had made. He said to the woman, “Did God really say, ‘You must not eat from any tree in the garden’?” – Genesis 3:1. Disguised as a crafty serpent, Satan came to tempt Eve. Satan at one time was an angel who rebelled against God and was thrown out of heaven. As a created being, Satan has definite limitations. Although he is trying to tempt everyone away from God, he will not be the final victor. In 3:14, 15, God promises that Satan will be crushed by one of the woman’s offspring, the Messiah.)
