Genesis 3:6 When the woman saw that the fruit of the tree was good for food and pleasing to the eye, and also desirable for gaining wisdom, she took some and ate it. She also gave some to her husband, who was with her, and he ate it.
The first duty of a Christian husband is to protect his family from the devil, but Adam chose to use his wife as a guinea pig instead. If she fell over dead, he would not have eaten the fruit. But since she survived, he thought it might be safe. Turning away from God can make us so selfish that we will hurt those we love in order to please ourselves.
Genesis 3:7 Then the eyes of both of them were opened, and they realized they were naked; so they sewed fig leaves together and made coverings for themselves.
This is how shame entered the world. Adam and Eve had nothing to hide before they sinned, but after they sinned they wanted to cover themselves. So they gathered fig leaves and stitched them together in a desperate attempt to cover their shame. If you have ever dreamed of being naked in public, you know how they felt.
But even if we have no physical shame, everyone carries moral shame. If everything we ever did became public information, we could never leave the house. One survey showed that fifty percent of adult males carry a secret so dark, that if it were exposed, it would destroy them.
Shame is a negative emotion, but it has a positive side. It means we are not as bad as we could be. As long as we have a sense of shame, we also have a conscience. The work of the Holy Spirit is to convince us of our sins (John 16:8), so that we can repent, and be restored to God.
