1 Corinthians 15:5-11

and that he was seen by Peter and then by the twelve apostles. After that, Jesus was seen by more than five hundred of the believers at the same time. Most of them are still living today, but some have died. Then he was seen by James and later by all the apostles. Last of all he was seen by me—as by a person not born at the normal time. All the other apostles are greater than I am. I am not even good enough to be called an apostle, because I persecuted the church of God. But God’s grace has made me what I am, and his grace to me was not wasted. I worked harder than all the other apostles. (But it was not I really; it was God’s grace that was with me.) So if I preached to you or the other apostles preached to you, we all preach the same thing, and this is what you believed.
