'Preach' in the Bible

For Christ sent me not to baptize, but to preach the Good News -- not in wisdom of words, so that the cross of Christ wouldn't be made void.

but we preach Christ crucified; a stumbling block to Jews, and foolishness to Greeks,

For if I preach the Good News, I have nothing to boast about; for necessity is laid on me; but woe is to me, if I don't preach the Good News.

What then is my reward? That, when I preach the Good News, I may present the Good News of Christ without charge, so as not to abuse my authority in the Good News.

Whether then it is I or they, so we preach, and so you believed.
