1 Corinthians 15:11

9 For I am the least of the apostles and am unworthy to be called an apostle, because I persecuted the church of God.

10 But by the grace of God I am what I am, and His grace to me was not in vain. No, I worked harder than all of them—yet not I, but the grace of God that was with me.

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

12 But if it is preached that Christ has been raised from the dead, how can some of you say that there is no resurrection of the dead?

13 If there is no resurrection of the dead, then not even Christ has been raised.

Do read the surrounding verses too, because the context often says more than a single verse.
