1 Corinthians 15:13

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

10But by the grace of God I am what I am. His grace which was given to me was not futile, but I worked more than all of them; yet not I, but the grace of God which was with me.

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

12Now 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?

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

14If Christ has not been raised, then our preaching is in vain and your faith also is in vain.

15Yes, we are also found false witnesses of God, because we testified about God that he raised up Christ, whom he didn’t raise up if it is true that the dead are not raised.

16For if the dead aren’t raised, neither has Christ been raised.

17If Christ has not been raised, your faith is vain; you are still in your sins.
