2 Peter 1:12-21
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.” 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.
Peter makes it clear that he walked with Jesus and was an eyewitness of His Majesty for three years as Jesus taught His disciples much about God and Himself...Peter acknowledges the Great Mysteries in his life -God, Jesus and the Holy Spirit...Peter also writes that 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...St. Peter does not write anything philosophical about the Holy Trinity but talks about himself being an eyewitness to Jesus and His Great Wonders, and how he heard God say,“This is My Son, whom I LOVE; with Him I AM well pleased.”...He and other disciples heard God say this on the sacred mountain...St. Peter knows all these mysteries he experienced as eternal realities about Jesus and God and the Holy Spirit, since he and the other disciples were eyewitness to these things...St. Peter would continue to talk about Jesus and His Truths to others as long as he was living...
Peter would leave it to later teachers and theologians to try to expound on this Great and Bright Mystery of God and the Trinity and the Holy Spirit...And Peter would teach others about Jesus until his death, and then those he and Jesus' Disciples taught would continue the Gospel of Jesus...
