'Preaching' in the Bible

For the Son of God, Jesus Christ, whom we were preaching among you, even I and Silvanus and Timothy, was not Yes and No, but in him is Yes.

For our preaching is not about ourselves, but about Christ Jesus as Lord, and ourselves as your servants through Jesus.

That is, that God was in Christ making peace between the world and himself, not putting their sins to their account, and having given to us the preaching of this news of peace.

For we stretch not ourselves beyond our measure, as though we reached not unto you: for we are come as far as to you also in preaching the gospel of Christ:

For if anyone comes preaching another Jesus from the one whose preachers we are, or if you have got a different spirit, or a different sort of good news from those which came to you, how well you put up with these things.

Or did I [perhaps] sin by humbling myself so that you might be exalted and honored, because I preached God’s gospel to you free of charge?
