The Gospel of Grace

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.
Gal. 1:6(Amplified Bible)

Why do we so quickly turn from the true Gospel of God's unmerited favor in Christ to a false gospel of works?

My guess is our pride. Our putrid pride makes us think that we can earn God's favor by what we do. It's time the church woke up and returned to the true Gospel! Christ has done it all!
There never was anything we could to do earn salvation or acceptance or favor from God. That's why Christ died in our place on the cross (paying the penalty we deserve). And after we come to Christ, we still can't do anything to keep our salvation or our acceptance or right standing before God. Again, Christ has done it all!

That is the truth that sets us free!!!
