8and last of all, as to one untimely born, He appeared to me also. 9For I am the least of the apostles, and not fit 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 toward me did not prove vain; but I labored even more than all of them, yet not I, but the grace of God with me.
