Paul worked harder than others to tell others about Jesus but he credits the grace of God for his success.
3 I passed on to you what was most important and what had also been passed on to me. Christ died for our sins, just as the Scriptures said. 4 He was buried, and he was raised from the dead on the third day, just as the Scriptures said. 5 He was seen by Peter[a] and then by the Twelve. 6 After that, he was seen by more than 500 of his followers at one time, most of whom are still alive, though some have died. 7 Then he was seen by James and later by all the apostles. 8 Last of all, as though I had been born at the wrong time, I also saw him. 9 For I am the least of all the apostles. In fact, I’m not even worthy to be called an apostle after the way I persecuted God’s church.
10 But whatever I am now, it is all because God poured out his special favor on me—and not without results. For I have worked harder than any of the other apostles; yet it was not I but God who was working through me by his grace. 11 So it makes no difference whether I preach or they preach, for we all preach the same message you have already believed.
