Gal 1:1-10 (NASB)
1 Paul, an apostle ( not sent from men nor through the agency of man, but through Jesus Christ and God the Father, who raised Him from the dead), 2 and all the brethren who are with me,
To the churches of Galatia:
3 Grace to you and peace from God our Father and the Lord Jesus Christ, 4 who gave Himself for our sins so that He might rescue us from this present evil age, according to the will of our God and Father, 5 to whom be the glory forevermore. Amen.

6 I am amazed that you are so quickly deserting Him who called you by the grace of Christ, for a different gospel; 7 which is really not another; only there are some who are disturbing you and want to distort the gospel of Christ. 8 But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed! 9 As we have said before, so I say again now, if any man is preaching to you a gospel contrary to what you received, he is to be accursed!
10 For am I now seeking the favor of men, or of God? Or am I striving to please men? If I were still trying to please men, I would not be a bond- servant of Christ.
