Studies in Genesis 3
Then the eyes of both were opened, and they knew that they were naked. And they sewed fig leaves together and made themselves loincloths. Genesis 3:7 ESV
As soon as Adam and Eve realized they were “naked” they tried to make coverings for their bodies. They used leaves because of the abundance of material and because they did not know how to make cloth or that they could kill and animal and use its skin.
Why did they see a need to cover themselves? Here are two possible answers.
First, they may have been ashamed and wanted to cover themselves to hide their shame. God has already told us they “were both naked and were not ashamed” (Genesis 2:25 ESV). When they ate the fruit of the tree of the knowledge of good and evil, what they expected to happen did not happen. Their eyes were opened but they were not changed or made better by the act. Eve expected something that would make her like God. Her superstitious expectation, fueled by the lies of the Deceiver, were unreasonable and could never be fulfilled. Adam, on the other hand, had no expectations. He ate because he wanted to eat.
For the first time, they felt guilt and shame and did not know how to react. So, they hid part of their bodies behind coverings. There was remorse but no repentance. Repentance comes from acknowledging guilt and the consequences of rebellion and then mentally and emotionally turning away from the act and motivation. Instead of admitting to each other what they had done was wrong, that they should not have eaten the fruit, they tried to cover over their sin and rebellion with a superficial, self-made fix.
Second, they may have wanted to undo what they had done but did not realize they could not. After their willful act, when their eyes were opened to a new and uncomfortable perspective, they may have wanted to go back to their original state and life. They did not know how. Perhaps they were beginning to realize they could not undo what had been done. Yet, their sin, their transgressions, needed covering.
It is the insanity of man to try to fix the unfixable. Only God can do the impossible. Once a transgression, a sin, is committed it cannot be undone. Yet, by the image of God in them, they inherently knew their sin needed covering. God did not create Man and give His image to turn His back on any person. Because of His love and desire for relationship He would cover their sin and restore their relationship with Him. But in His way and at His time and at a great cost to Him.
It is the gospel which declares God has done that which Man cannot do.
