1 Corinthians 15:7-11

then He appeared to James, then to all the apostles;

and last of all, as to one untimely born, He appeared to me also.

For I am the least of the apostles, and not fit to be called an apostle, because I persecuted the church of God.

But 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.

Whether then it was I or they, so we preach and so you believed.
