1st Corinthians 15:12

9 For I am the least of the apostles, that am not meet 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 which was bestowed upon me was not found vain; but I labored more abundantly than they all: yet not I, but the grace of God which was with me.

11 Whether then [it be] I or they, so we preach, and so ye believed.

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

13 But if there is no resurrection of the dead, neither hath Christ been raised:

14 and if Christ hath not been raised, then is our preaching vain, your faith also is vain.

15 Yea, we are found false witnesses of God; because we witnessed of God that he raised up Christ: whom he raised not up, if so be that the dead are not raised.
