Galatians 1:1-9.

Gospel means good news and the good news of the gospel is that grace and peace from God is found in Jesus Christ who gave himself for our sins. This is the gospel: Jesus + Nothing = My only hope of salvation. To tweak this gospel formula results in a distortion that is no gospel at all. Paul calls the Galatians and us back to the purity of God's grace found in Jesus Christ alone.
