Galatians 1

Paul warned the Galatians about people who came teaching false gospels. He said they take the true gospel of Christ and distort it. The true gospel is something that is not of men, but of God and is not preached in order to win the favor of men, but to honor and glorify God.

God's message of salvation is non-negotiable. We cannot add to it or take away from it to suit ourselves or others. The only choice we have is to accept it or reject it. Once we make changes, we have rejected it by default. Anyone who changes the word of God and tries to share it with others is a false teacher and should be exposed as such. Believers need to be wise enough to spot false teachers and avoid them so they will not be led astray.
