9 For I am the least of the apostles, who am not fit to be called apostle, because I have persecuted the assembly of God.
10 But by God's grace I am what I am; and his grace, which was towards me, has not been vain; but I have laboured more abundantly than they all, but not I, but the grace of God which was with me.
11 Whether, therefore, I or they, thus we preach, and thus ye have believed.
12 Now if Christ is preached that he is raised from among the dead, how say some among you that there is not a resurrection of those that are dead?
13 But if there is not a resurrection of those that are dead, neither is Christ raised:
14 but if Christ is not raised, then, indeed, vain also is our preaching, and vain also your faith.
15 And we are found also false witnesses of God; for we have witnessed concerning God that he raised the Christ, whom he has not raised if indeed those that are dead are not raised.
