18 When this voice was conveyed from heaven, we ourselves heard it, for we were with him on the holy mountain.
19 Moreover, 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.
20 Above all, you do well if you recognize this: No prophecy of scripture ever comes about by the prophet’s own imagination,
21 for no prophecy was ever borne of human impulse; rather, men carried along by the Holy Spirit spoke from God.
