1 Corinthians 15:8-11

8Last of all, as though to one born at the wrong time, he appeared to me also.

9For I am the least of the apostles, unworthy 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 to me has not been in vain. In fact, I worked harder than all of them – yet not I, but the grace of God with me.

11Whether then it was I or they, this is the way we preach and this is the way you believed.
