Justified by the Law, or Justified by Faith?

3 O foolish Galatians, who has bewitched you, before whose eyes Jesus Christ was publicly portrayed as having been crucified? ² I want only to learn this from you: Did you receive the Spirit by the works of the law, or by the hearing of faith? ³ Are you so foolish? Having begun by the Spirit, are you now trying to be made complete by the flesh? ⁴ Have you suffered so many things for nothing—if indeed also it was for nothing? ⁵ Therefore does the one who gives you the Spirit and who works miracles among you do so by the works of the law, or by the hearing of faith?
