Galatians 3:2-4

So answer me this: Did the Holy Spirit come to you as a reward for keeping Jewish laws? No, you received him as a gift because you believed in the Messiah. Your new life began when the Holy Spirit gave you a new birth. Why then would you so foolishly turn from living in the Spirit by trying to finish by your own works? Have you endured so many trials and persecutions for nothing?
