[12] So I will always remind you of these things, even though you know them and are firmly established in the truth you now have. [13] I think it is right to refresh your memory as long as I live in the tent of this body, [14] because I know that I will soon put it aside, as our Lord Jesus Christ has made clear to me. [15] And I will make every effort to see that after my departure you will always be able to remember these things. [16] For we did not follow cleverly devised stories when we told you about the coming of our Lord Jesus Christ in power, but we were eyewitnesses of his majesty. [17] He received honor and glory from God the Father when the voice came to him from the Majestic Glory, saying, “This is my Son, whom I love; with him I am well pleased.” [18] We ourselves heard this voice that came from heaven when we were with him on the sacred mountain. [19] We also have the prophetic message as something completely reliable, and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts. [20] Above all, you must understand that no prophecy of Scripture came about by the prophet’s own interpretation of things. [21] For prophecy never had its origin in the human will, but prophets, though human, spoke from God as they were carried along by the Holy Spirit.
