The Gospel (1 Corinthians 15, Romans 3)

Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; 2By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. 3For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; 4And that he was buried, and that he rose again the third day according to the scriptures: 1 Corinthians 15:1-4Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; 26To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus. 27Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith. 28Therefore we conclude that a man is justified by faith without the deeds of the law. Romans 3:25-28
