1 Corinthians 15:8-12
15:8 Last of all, as though to one born at the wrong time,

15:9 For I am the least of the apostles, unworthy to be called an apostle, because I persecuted the church of God.
15:10 But 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.
15:11 Whether then it was I or they, this is the way we preach and this is the way you believed.
