Galatians 3:10-12, 21-25

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.” So it is clear that no one can be made right with God by trying to keep the law. For the Scriptures say, “It is through faith that a righteous person has life.” This way of faith is very different from the way of law, which says, “It is through obeying the law that a person has life.”

Is there a conflict, then, between God’s law and God’s promises? Absolutely not! If the law could give us new life, we could be made right with God by obeying it. But the Scriptures declare that we are all prisoners of sin, so we receive God’s promise of freedom only by believing in Jesus Christ. Before the way of faith in Christ was available to us, we were placed under guard by the law. We were kept in protective custody, so to speak, until the way of faith was revealed. 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. And now that the way of faith has come, we no longer need the law as our guardian.
