1st Corinthians 15:10

7 Then he appeared to James, then to all the apostles,

8 and last of all, as to the child born at the wrong time, he appeared to me also.

9 For I am the least of the apostles, who is not worthy to be called an apostle, because I persecuted the assembly of God.

10 But by the grace of God I am what I am. His grace which was bestowed on me was not found vain, but I worked more than all of them; yet not I, but the grace of God which was with me.

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

12 Now if Christ is preached, that he has been raised from the dead, how do some among you say that there is no resurrection of the dead?

13 But if there is no resurrection of the dead, neither has Christ been raised.
