The first consequence of Adam’s and Eve’s sin mentioned in Genesis 3:7 is that “the eyes of both were opened, and they knew that they were naked. And they sewed fig leaves together and made themselves loincloths.” 

Suddenly they are self-conscious about their bodies. Before their rebellion against God, there was no shame. “The man and his wife were both naked and were not ashamed” (Genesis 2:25). Now there is shame. Why?

There is no reason to think that it’s because they suddenly became ugly. Their beauty wasn’t the focus in Genesis 2:25, and their ugliness is not the focus here in Genesis 3:7. Why then the shame? Because the foundation of covenant-keeping love collapsed. And with it the sweet, all-trusting security of marriage disappeared forever.

The foundation of covenant-keeping love between a man and a woman is the unbroken covenant between them and God—God governing them for their good and they enjoying him in that security and relying on him. When they ate from the tree of the knowledge of good and evil, that covenant was broken and the foundation of their own covenant-keeping collapsed.

They experienced this immediately in the corruption of their own covenant love for each other. It happened in two ways. Both relate to the experience of shame. In the first case, the one viewing my nakedness is no longer trustworthy, so I am afraid I will be shamed. In the second, I myself am no longer at peace with God, but I feel guilty and defiled and unworthy—I deserve to be shamed.

In the first case, I am self-conscious of my body, and I feel vulnerable to shame because I know Eve has chosen to be independent from God. She has made herself central in the place of God. She is essentially now a selfish person. From this day forward, she will put herself first. She is no longer a servant. So she is not safe. And I feel vulnerable around her, because she is very likely to put me down for her own sake. So suddenly my nakedness is precarious. I don’t trust her any more to love me with pure covenant-keeping love. That’s one source of my shame.

The other source is that Adam himself, not just his spouse, has broken covenant with God. If she is rebellious and selfish, and therefore unsafe, so am I. But the way I experience it in myself is that I feel defiled and guilty and unworthy. That’s, in fact, what I am. Before the Fall, what was and what ought to have been were the same. But now, what is and what ought to be are not the same.

I ought to be humbly and gladly submissive to God. But I am not. This huge gap between what I am and what I ought to be colors everything about me—including how I feel about my body. So my wife might be the safest person in the world, but now my own sense of guilt and unworthiness makes me feel vulnerable. The simple, open nakedness of innocence now feels inconsistent with the guilty person that I am. I feel ashamed.
