From John Piper’s Momentary Marriage, pg. 37.
If they were naked and shame-free before the Fall, and if they put on clothes to minimize their shame after the Fall, then what is God doing by clothing them even better than they can clothe themselves? I think the answer is that he is doing something with a negative message and something with a positive message.
Negatively, he is saying: You are not what you were, and you are not what you ought to be. The chasm between what you are and what you ought to be is huge. Covering yourself with clothing is a right response to this—not to conceal it, but to confess it. Henceforth, you shall wear clothing, not to conceal that you are not what you should be, but to confess that you are not what you should be. One practical implication of this is that public nudity today is not a return to innocence but rebellion against moral reality. God ordains clothes to witness to the glory we have lost, and it is added rebellion to throw them off.
And for those who rebel in the other direction and make clothes themselves a means of power and prestige and attention-getting, God’s answer is not a return to nudity but a return to simplicity (1 Tim. 2:9–10; 1 Peter 3:4–5). Clothes are not meant to make people think about what is under the clothes. Clothes are meant to direct attention to what is not under them: merciful hands that serve others in the name of Christ, beautiful feet that carry the gospel where it is needed, and the brightness of a face that has beheld the glory of Jesus.
