What does the Bible say about the two religions in Genesis 9?

In Genesis 9, we see the contrast between the religion of flesh, embodied by Ham, and the religion of faith, exemplified by Shem and Japheth. Ham saw the nakedness of his father Noah and boasted of it, representing the flesh's tendency to point out sin without offering any remedy. In contrast, Shem and Japheth took a garment and covered Noah's nakedness, symbolizing the grace of God that covers our sins. Thus, the text illustrates the need for a Savior and the reality that true righteousness comes not from our works, but from faith in God's provision for our sin through Christ.
