2 Peter 1:20-21 "Knowing this first, that no prophecy of the noscripture is of any private interpretation. "For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost. What does 2 Peter 1:20 & 21mean? 🔽🔽

In verses 16 through 18, Peter referred to his witness of the "transfiguration" of Jesus (Matthew 17:1–13). This was Peter's most powerful personal confirmation of the prophecies in Scripture about the Messiah. Seeing this event proved, in no uncertain terms, that what Peter had heard from Jesus was absolutely true. The confirmation of those prophecies, and the reality of God, also confirms the prophecies yet to be fulfilled. This includes those about Jesus' return as judge and king.

Peter has been speaking of invented stories and myths, specifically saying his claims are neither of these. Here, Peter emphasizes the fact that the power of prophecy does not come from some human interpretation of events. In other words, the prophecies of Scripture were not "cleverly devised" stories (2 Peter 1:16) or the best guesses of insightful men. These are claims which, if shown to be true, can only be the product of inspiration by God. This is the theme Peter explores in verse 21. Here, he repeats his statement from the previous verse: These prophecies were not invented by human minds. They were not "cleverly devised" stories (2 Peter 1:16) meant to deceive, and they were not insightful human predictions meant to encourage. Rather, these prophecies came straight from the mind of God. The prophets spoke God's Words as they were carried along (or "moved") by the Holy Spirit. This is proven, in part, by the fact that they are confirmed. And, more powerfully, by the fact that they are not simply guesses or speculation. These are specific prophecies, which were specifically fulfilled.

In other words, the prophecies of Scripture are the words of God about the actions of God. And God always accomplishes what He sets out to do. (Taken from Bibleref.com)
