I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. ~ Galatians 1:6-7 KJV

I am surprised and astonished that you are so quickly turning renegade and deserting Him Who invited and called you by the grace (unmerited favor) of Christ (the Messiah) [and that you are transferring your allegiance] to a different [even an opposition] gospel. Not that there is [or could be] any other [genuine Gospel], but there are [obviously] some who are troubling and disturbing and bewildering you [with a different kind of teaching which they offer as a gospel] and want to pervert and distort the Gospel of Christ (the Messiah) [into something which it absolutely is not]. ~ Galatians 1:6-7 AMP
