Galatians 1:1-10; NKJV
1 Paul, an apostle (not from men nor through 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 the Father and our Lord Jesus Christ,
4 who gave Himself for our sins, that He might deliver us from this present evil age, according to the will of our God and Father,
5 to whom be glory forever and ever. Amen.
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.
To turn away from the gospel of Christ to a different gospel is to turn away from Him. The facts, commands and promises of the gospel of Christ matter. If you turn away from the doctrine of Christ, you are turning away from Him.
