1 Corinthians 15:10-12

10 But by the grace of God I am what I am; and his grace towards me was not in vain, for I laboured more abundantly than they all, yet not I, but the grace of God which was with me.

11 Therefore, whether [it were] I or they, so we preach, and so ye believed.

12 Now if [the] Christ is preached that rose from the dead, how say some among you that there is no resurrection of the dead?
