Paul saw himself as Christs herald. When he describes himself as an appointed preacher of the gospel (2 Tim. 1:11), the noun he uses means a herald, a person who makes public announcements on anothers behalf. When he declares “we preach Christ crucified,” the verb he uses denotes the heralds appointed activity of blazoning abroad what he has been told to make known. When Paul speaks of “my preaching” and “our preaching” and lays it down that after the worlds wisdom had rendered the world ignorant of God “it pleased God through the folly of what we preach to save those who believe,” the noun he uses doesnt mean the activity of announcing, but the thing announced, the proclamation itself, the message declared.
Paul, in his own estimation, was not a philosopher, not a moralist, not one of the worlds wise men, but simply Christs herald. His royal master had given him a message to proclaim; his whole business was to deliver that message with exact and studious faithfulness, adding nothing, altering nothing, and omitting nothing. And he was to deliver it not as another of peoples bright ideas, needing to be beautified with the cosmetics and high heels of fashionable learning in order to make people look at it, but as a word from God spoken in Christs name, carrying Christs authority and authenticated in the hearers by the convincing power of Christs Spirit (1 Cor. 2:1-5).
