1 Corinthians 15:9–10

9 For I am mthe least of the apostles, who am not worthy to be called an apostle, because nI persecuted the church of God. 10 But oby the grace of God I am what I am, and His grace toward me was not in vain; but I labored more abundantly than they all, pyet not I, but the grace of God which was with me.
