And the LORD God made for Adam and for his wife garments of skins and clothed them. – Genesis 3:21
Immediately after the Fall into sin, Adam and Eve heard the sound of God walking in the garden, and now aware of their own nakedness, hid from Him in the trees of Eden. God called out to Adam, and he answered, later admitting to the sin he committed by eating of the tree and corrupting God’s perfect creation permanently (until the creation of a new heaven and a new earth), but not without passing the blame to Eve – and perhaps to God himself “The woman whom you gave to be with me”(!)
Nevertheless, as His first created people, whom he walked and talked with, played blame games as if God did not already know exactly what had happened, God showed mercy immediately.
When Adam and Eve became aware of their nakedness, God gave them clothes He made. Yet it was not the only clothing God provided. Not only were the bodies of Adam and Eve naked, their spirits were as well. Surely as God remedied their physical nakedness, he would provide a spiritual cover as well. The latter was and is the greater gift. God clothed Adam and Eve with His own righteousness, taking their sin upon Himself and giving them the garments of eternal life. All this by the suffering of Christ on the cross, He has done for us too.

and kind in all his works.” – Psalm 145:17
