An old preacher once advised his younger brethren to preach:
“A full Gospel - Christ & nothing less;
A plain gospel - Christ & nothing more;
A pure gospel - Christ & nothing else.”
- A. P. Gibbs (moreillustrations.com)
Mk 16:16 (NCV): “Anyone who believes and is baptized will be saved, but anyone who does not believe will be punished.”
“A gospel that does not confront sin is not the gospel of Jesus Christ.” - John MacArthur.
2 Cor 4:3 (CEB): “And even if our gospel is veiled, it is veiled to those who are on the road to destruction.”
“In contradistinction to the Gospel of Christ, the gospel of Satan teaches salvation by works.” - A.W. Pink.
