Galatians 3:10, 13, 24

But those who depend on the law to make them right with God are under his curse, for the Scriptures say, “Cursed is everyone who does not observe and obey all the commands that are written in God’s Book of the Law.”

But Christ has rescued us from the curse pronounced by the law. When he was hung on the cross, he took upon himself the curse for our wrongdoing. For it is written in the Scriptures, “Cursed is everyone who is hung on a tree.”

Let me put it another way. The law was our guardian until Christ came; it protected us until we could be made right with God through faith.
