You stupid people of Galatia! Who put you under an evil spell? Wasn't Christ Jesus' crucifixion clearly described to you?
I want to learn only one thing from you. Did you receive the Spirit by your own efforts to live according to a set of standards or by believing what you heard?
Are you that stupid? Did you begin in a spiritual way only to end up doing things in a human way?
Did you suffer so much for nothing? [I doubt] that it was for nothing!
Does God supply you with the Spirit and work miracles among you through your own efforts or through believing what you heard?
