Galatians 1:6-10 (NKJV)
6 I marvel that you are turning away so soon from Him who called you in the grace of Christ, to a different gospel,
7 which is not another; but there are some who trouble you and want to pervert the gospel of Christ.
8 But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed.
9 As we have said before, so now I say again, if anyone preaches any other gospel to you than what you have received, let him be accursed.
10 For do I now persuade men, or God? Or do I seek to please men? For if I still pleased men, I would not be a bondservant of Christ.
