'Preach the Gospel' in the Bible

Then He said to them, “Go into all the world and preach the gospel to the whole creation.

For Christ did not send me to baptize, but to evangelize—not with clever words, so that the cross of Christ will not be emptied of its effect.

In the same way, the Lord has commanded that those who preach the gospel should earn their living by the gospel.

For if I preach the gospel, I have no reason to boast, because an obligation is placed on me. And woe to me if I do not preach the gospel!

What then is my reward? To preach the gospel and offer it free of charge and not make full use of my authority in the gospel.

so that we may proclaim the good news to the regions beyond you, not boasting about what has already been done in someone else’s area of ministry.
