9 For I am the least of the Apostles. I am not worthy 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 in me has not been empty, since I have labored more abundantly than all of them. Yet it is not I, but the grace of God within me.
11 For whether it is I or they: so we preach, and so you have believed.
12 Now if Christ is preached, that he rose again from the dead, how is it that some among you say that there is no resurrection of the dead?
13 For if there is no resurrection of the dead, then Christ has not risen.
14 And if Christ has not risen, then our preaching is useless, and your faith is also useless.
15 Then, too, we would be found to be false witnesses of God, because we would have given testimony against God, saying that he had raised up Christ, when he had not raised him up, if, indeed, the dead do not rise again.
