What happened when God called Moses up into the mountain in Exodus?
God gave the Law to Moses on the mountain. Moses carried it down and delivered it to the nation of Israel. Consequently, Israel came under the Law, not the rest of the world. As Romans 3 says, all the world came under the Law's condemnation, proving no one righteous.
Les explains that when God called Moses up into the mountain in Exodus, He gave the Law to Moses. Moses then took it down the mountain and gave it to the nation of Israel. So Israel came under the Law, not the rest of the world, just Israel. But as Romans 3 says, all the world came under the condemnation power of the Law, proving no one is righteous. The modus operandi, or mode of operation, of the Law was given only to Israel. Then in Galatians and Paul's account of his apostleship, Paul is the central character, and to him were revealed doctrines not of Law but of Grace. Grace is not confined to Israel but is primarily to the Gentiles, while also including the Jew.
