'Preach the Gospel' in the Bible

He said to them, "Go into all the world and preach the gospel to every creature.

Thus I am eager also to preach the gospel to you who are in Rome.

For Christ did not send me to baptize, but to preach the gospel -- and not with clever speech, so that the cross of Christ would not become useless.

For if I preach the gospel, I have no reason for boasting, because I am compelled to do this. Woe to me if I do not preach the gospel!

What then is my reward? That when I preach the gospel I may offer the gospel free of charge, and so not make full use of my rights in the gospel.

so that we may preach the gospel in the regions that lie beyond you, and not boast of work already done in another person's area.
