But if one of you suffers for being a Christian, let him not be ashamed; but let him glorify God in this matter.

 Peter is thinking of the two great activities of the Christian Church, preaching and practical service. The word he uses for sayings is logia ( G3048) . That is a word with a kind of divine background. The heathen used it for the oracles which came to them from their gods; the Christians used it for the words of scripture and the words of Christ. So Peter is saying, "If a man has the duty of preaching, let him preach not as one offering his own opinions or propagating his own prejudices, but as one with a message from God." It was said of one great preacher: "First he listened to God, and then he spoke to men." It was said of another that ever and again he paused, "as if listening for a voice." There lies the secret of preaching power.
