Galatians 3:3-6

Are you so foolish? After beginning by means of the Spirit, are you now trying to finish by means of the flesh? Have you experienced so much in vain—if it really was in vain? So again I ask, does God give you his Spirit and work miracles among you by the works of the law, or by your believing what you heard? So also Abraham “believed God, and it was credited to him as righteousness.”
