1 Corinthians 15:9-11
1 Corinthians 15: 9 to 11
9 For I am the least of the apostles and am not fit 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 toward me was not in vain. I labored more abundantly than all of them, yet not I, but the grace of God which was with me.
11 Therefore, whether it was I or they, so we preach and so you believed.
