1 Corinthians 15:9-11

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. 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. So it makes no difference whether I preach or they preach, for we all preach the same message you have already believed.
