You people in Galatia were told very clearly about the death of Jesus Christ on the cross. But you were foolish; you let someone trick you.
Tell me this one thing: How did you receive the Holy Spirit? Did you receive the Spirit by following the law? No, you received the Spirit because you heard the Good News and believed it.
You began your life in Christ by the Spirit. Now are you trying to make it complete by your own power? That is foolish.
Were all your experiences wasted? I hope not!
Does God give you the Spirit and work miracles among you because you follow the law? No, he does these things because you heard the Good News and believed it.
The Scriptures say the same thing about Abraham: "Abraham believed God, and God accepted Abraham's faith, and that faith made him right with God."
