1 Corinthians 15:9-11

Revised Geneva Translation

⁹ For I am the least of the Apostles, who is not fit to be called an Apostle, because I persecuted the Church of God.

¹⁰ But by the grace of God I am that I am. And His grace which is in me, was not in vain. But I labored more abundantly than they all; yet not I, but the grace of God which is with me.

¹¹ Therefore, whether it was me or them, so we preach and so have you believed.
