In No Other Gospel (Galatians 1:1–9), we are confronted with the urgent reality that the message of the gospel is not ours to reshape—it is God’s to reveal. Paul writes with shock and intensity because the Galatians were not just drifting in doctrine; they were deserting God Himself by embracing a distorted gospel. This message explores how the true gospel comes from God, centers on Christ’s finished work, and alone has the power to rescue sinners. Through vivid illustrations and clear exposition, we see that every false gospel ultimately replaces Christ with self and cannot save. The stakes could not be higher: to alter the gospel is to lose it entirely. Yet the good news remains—Jesus is sufficient, and His grace alone delivers us from sin and this present evil age. This sermon calls us to guard the gospel, live in its grace, and boldly proclaim it to a world in desperate need of rescue.
