1 Corinthians 15:1-11 Christian Standard Bible (CSB)
Resurrection Essential to the Gospel
15 Now I want to make clear for you, brothers and sisters, the gospel I preached to you, which you received, on which you have taken your stand 2 and by which you are being saved, if you hold to the message I preached to you—unless you believed in vain. 3 For I passed on to you as most important what I also received: that Christ died for our sins according to the Scriptures, 4 that he was buried, that he was raised on the third day according to the Scriptures, 5 and that he appeared to Cephas, then to the Twelve. 6 Then he appeared to over five hundred brothers and sisters at one time; most of them are still alive, but some have fallen asleep. 7 Then he appeared to James, then to all the apostles. 8 Last of all, as to one born at the wrong time,[a] he also appeared to me.
9 For I am the least of the apostles, not worthy to be called an apostle, because I persecuted the church of God. 10 But by the grace of God I am what I am, and his grace toward me was not in vain. On the contrary, I worked harder than any of them, yet not I, but the grace of God that was with me. 11 Whether, then, it is I or they, so we proclaim and so you have believed.
