1 Corinthians 15:8-11

8And last of all he was seen by me also, as by one born out of due time.1 9For I am the least of the apostles, who am not worthy to be called an apostle, because I persecuted the church of God. 10But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me. 11Therefore whether it was I or they, so we preach, and so ye believed.
