You foolish Galatians! Who has bewitched you? It was before your eyes that Jesus Christ was publicly exhibited as crucified!
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?
Are you so foolish? Having started with the Spirit, are you now ending with the flesh?
Did you experience so much for nothing?—if it really was for nothing.
Well then, does God supply you with the Spirit and work miracles among you by your doing the works of the law, or by your believing what you heard?
References for Galatians 3:5
Just as Abraham "believed God, and it was reckoned to him as righteousness,"
so, you see, those who believe are the descendants of Abraham.
