1 Corinthians 1:23

23 But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness;

1 Corinthians 9:27

27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.

1 Corinthians 15:11

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

1 Corinthians 15:12

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