1 Corinthians 15:8-10

8 and last of all, as to the child born at the wrong time, he appeared to me also.  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 bestowed on me was not futile, but I worked more than all of them; yet not I, but the grace of God which was with me.
