God continues to forbid practices that are not in His people’s best interest. Rather, God promotes His ways which lead to harmony with God and others.
God outlines a list of incestuous sexual sins and forbids His people to engage in them as was common in the lands of Egypt and Canaan. The phrase “uncover one’s nakedness” means to engage in sexual intimacy with a person (including but not limited to intercourse). Uncovering the nakedness of one’s spouse within the covenant of marriage produces oneness. However, having forbidden sexual relations is usually in order to exploit another for personal sexual gratification, and is forbidden. Here it is forbidden particularly within families.
God’s law presents to us an ideal way to live in harmony with God and our fellow humans by defining what is right and wrong. As our creator, God knows this better than any human. In pronouncing His ways, He is making clear the path to our ultimate best interest.
God tells the Israelites through Moses that His ways are in their best interest. The ways of the Egyptians and the Canaanites, which are the ways of their sinful flesh, are not in their best interest. Those ways lead to death while His ways lead to life and peace.
The LORD promises to restore Israel along with her fortunes. He will reverse all the curses that fall on her and sow her for Himself in the land.
The LORD describes His judgment on Israel because she goes after other gods. Since Israel credits the fertility gods such as Baal for providing for her needs, the Suzerain God declares that He will prevent her from all means of access to cause her to return to Him.
The LORD urges His children to denounce their mother for her shameful behavior, lest they follow her and fall under the same judgment that awaits her.
The LORD anticipates a time when He will once again accept Israel as His people and have compassion on them.
Peter shows that Jesus was the prophet whom God promised to raise up for Israel, but that anyone who does not listen to the prophet will be destroyed. All the other prophets of God spoke of this period, where the Jews could decide to obey God’s Messiah, for they are part of a covenant with God. God sent Jesus ultimately to bless the people of Israel and reconcile them with God, if they will repent.
Peter says that Jesus fulfilled the prophecies of the Old Testament, that He was destined to suffer. He calls on his Jewish audience to repent of their sin and return to God, so that they will be forgiven, and so that Jesus will return and start His kingdom, and refresh and restore the earth.
