Also for Adam and his wife the LORD God made tunics of skin,

.... and clothed them (Genesis Gen. 3:21). After their disobedience  Adam and Eve knew they were naked; and they sewed fig leaves together and made themselves coverings (3:6, 7).  Looking deeper there are two things that we will see here. The first is that  nakedness will be seen from time to time as a metaphor for sin,  guilt and shame. The second is that it is God and only God who can cover this metaphorical nakedness. Adam and Eve had tried to hide their nakedness.  However “there is no creature hidden from His sight, but all things are naked and open to the eyes of Him to whom we must give account” (Hebrews 4:13). And in the resurrection we will be clothed with immortality so that we shall not be found naked (2 Corinthians 5:3).

Adam and Eve had made a futile attempt to cover their nakedness, their sin and their guilt, and shame, with fig leaves (3:7). As a race we use various means to attempt to cover our sin, we suppress it,  pretend it does't exist or that it does not bother us, we blame others for laying guilt trips on us etc.  In Proverbs 28:13 we read “He who covers his sins will not prosper.” David cried out “When I kept silent about my sin, my body wasted away through my groaning all the day long” (Psalm 32:3). Researchers increasingly are finding  connections between guilt and shame and health, mental,  physical and emotional.

The cure for guilt is to be forgiven, and ultimately God is the only one who can forgive. After committing adultery and a subsequent murder (2 Samuel 11, 12),  David declared “Against You only have I sinned” (Psalm 51:4). He was not prospering,  his sin was ever before him (verse 3). The second half of Proverbs 28:13 then reads  “but whoever confesses and forsakes them will have mercy.”
When we confess our sins, our guilt and shame are covered.  David again “Blessed is he whose transgression is forgiven, whose sin is covered (1 John 1:9: Psalm. 32:1). The believer is clothed with the garments of salvation, and covered with the robe of righteousness (Isaiah 61:10).  We have a part to play. As we the church,  the bride of Christ (Ephesians 5:27),  make ourselves ready (sanctification), it is granted to us to “be arrayed in fine linen, clean and bright, for the fine linen is the righteous acts of the saints” (Revelation 19:7, 8).

In order for God to clothe Adam and Eve in animal skins, the animals had to die.  This too points to a deeper meaning of the text. Ultimately, as the Scripture tells us,  without the shedding of blood there is no forgiveness of sin,  no covering with His robe of righteousness (Hebrews 9:22). This first act of sacrifice foreshadowed the animal sacrifices that were prescribed under the Law. These animal sacrifices are themselves “a shadow of things to come, but the substance is of Christ” (Colossians 2:17).  That is Jesus Christ Himself is the Lamb of God that takes away the sins of the World (John 1:29).

Lord Jesus, perhaps is it no coincidence that the chorus “I'm forever grateful” is on my heart this morning.  I'm forever grateful that You came to seek and save the lost (Luke 19:10). In view of Your tender mercies Lord we present our bodies again this morning as a living sacrifices Holy and acceptable to You,  and we give Your the glory in Your precious Name Amen
