1 Corinthians 15:9-10

WEB(i) 9 For I am the least of the apostles, who is not worthy to be called an apostle, because I persecuted the assembly of God. 10 But by the grace of God I am what I am. His grace which was given to me was not futile, but I worked more than all of them; yet not I, but the grace of God which was with me.
