Galatians 3:2-5

3:2 The only thing I want to learn from you is this: Did you receive the Spirit by doing the works of the law or by believing what you heard? 3:3 Are you so foolish? Although you began with the Spirit, are you now trying to finish by human effort? 3:4 Have you suffered so many things for nothing? – if indeed it was for nothing. 3:5 Does God then give you the Spirit and work miracles among you by your doing the works of the law or by your believing what you heard?
