9. For I am the least of the apostles, who 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 which was bestowed upon me, was not in vain; but I labored more abundantly than they all: yet not I, but the grace of God which was with me.
11. Therefore whether it was I or they, so we preach, and so ye believed.
12. Now if Christ is preached that he rose 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, then is Christ not raised.
14. And if Christ is not raised, then is our preaching vain, and your faith is also vain.
