1 Corinthians 15:9-11

New Revised Standard Version, Anglicised

⁹ For I am the least of the apostles, unfit 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 towards me has not been in vain. On the contrary, I worked harder than any of them—though it was not I, but the grace of God that is with me. ¹¹ Whether then it was I or they, so we proclaim and so you have come to believe.
