Galatians 1:6-8 NIV

[6] I am astonished that you are so quickly deserting the one who called you to live in the grace of Christ and are turning to a different gospel— [7] which is really no gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ. [8] But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let them be under God’s curse!
