Galatians 3:17-18

This means that the covenant between God and Abraham was fulfilled in Messiah and cannot be altered. Yet the written law was not even given to Moses until 430 years after God had “signed” his contract with Abraham! The law, then, doesn’t supersede the promise since the royal proclamation was given before the law. If that were the case, it would have nullified what God said to Abraham. We receive all the promises because of the Promised One—not because we keep the law!
