2 Peter 1:12-21 New King James Version (NKJV)
Peter’s Approaching Death
12 For this reason I will not be negligent to remind you always of these things, though you know and are established in the present truth. 13 Yes, I think it is right, as long as I am in this [a]tent, to stir you up by reminding you, 14 knowing that shortly I must [b]put off my tent, just as our Lord Jesus Christ showed me. 15 Moreover I will be careful to ensure that you always have a reminder of these things after my [c]decease.
The Trustworthy Prophetic Word
16 For we did not follow cunningly devised fables when we made known to you the power and coming of our Lord Jesus Christ, but were eyewitnesses of His majesty. 17 For He received from God the Father honor and glory when such a voice came to Him from the Excellent Glory: “This is My beloved Son, in whom I am well pleased.” 18 And we heard this voice which came from heaven when we were with Him on the holy mountain.
19 [d]And so we have the prophetic word confirmed, which you do well to heed as a light that shines in a dark place, until the day dawns and the morning star rises in your hearts; 20 knowing this first, that no prophecy of Scripture is of any private [e]interpretation, 21 for prophecy never came by the will of man, but [f]holy men of God spoke as they were moved by the Holy Spirit.
2 Peter 1:12-21 New International Version (NIV)
Prophecy of Scripture
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.”[a] 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.
