From the very beginning, humanity tried to cover its own shame — and from the very beginning, it was not enough. In Genesis 3, we see Adam and Eve reach for fig leaves, then hide behind trees, desperately trying to conceal what only God could fix.
The truth is simple but profound: the only thing that replaces guilt is innocence. You cannot make yourself innocent once you are guilty. But God, even in the moment of judgment, made tunics of animal skin to cover Adam and Eve — something innocent had to shed its blood to cover their shame. That is the picture of the cross.
Genesis 3:15 gives us the first promise of a Savior — the seed of the woman who would crush the serpent's head. That promise was fulfilled in Jesus Christ, whose shed blood is the only covering that truly works.
