O foolish Galatians! Who has bewitched you that you should not obey the truth, before whose eyes Jesus Christ was clearly portrayed among you as crucified?
This only I want to learn from you: Did you receive the Spirit by the works of the law, or by the hearing of faith?
Are you so foolish? Having begun in the Spirit, are you now being made perfect by the flesh?
Have you suffered so many things in vain--if indeed it was in vain?
Therefore He who supplies the Spirit to you and works miracles among you, does He do it by the works of the law, or by the hearing of faith?--
just as Abraham "believed God, and it was accounted to him for righteousness."
References for Galatians 3:6
Therefore know that only those who are of faith are sons of Abraham.
