In the dispensation of the grace of God, the gospel which saves us today found in 1 Corinthians 15:1-4
1 Corinthians 15:1-4 – 1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; 2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. 3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; 4 And that he was buried, and that he rose again the third day according to the scriptures:Faith + Nothing = SalvationFaith + Nothing = Salvation
Believing this, and this alone, is what saves. If you attempt to add anything to this for salvation in the dispensation of grace, you’re adding to the gospel and therefore, you’re preaching another gospel.
