16For we did not follow cleverly concocted fables when we made known to you the power and return of our Lord Jesus Christ; no, we were eyewitnesses of his grandeur. 17For he received honor and glory from God the Father, when that voice was conveyed to him by the Majestic Glory: “This is my dear Son, in whom I am delighted.” 18When this voice was conveyed from heaven, we ourselves heard it, for we were with him on the holy mountain. 19Moreover, we possess the prophetic word as an altogether reliable thing. You do well if you pay attention to this as you would to a light shining in a murky place, until the day dawns and the morning star rises in your hearts. 20Above all, you do well if you recognize this: No prophecy of scripture ever comes about by the prophet’s own imagination, 21for no prophecy was ever borne of human impulse; rather, men carried along by the Holy Spirit spoke from God.
