1 Corinthians 15:9-11

21st Century King James Version

⁹ For I am the least of the apostles, not meet 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 which was bestowed upon me was not in vain; but I labored more abundantly than they all — yet not I, but the grace of God which was with me.

¹¹ Therefore whether it were I or they, so we preach, and so ye believed.
