Charles Spurgeon Commentary 2 Peter 1:20-21

"knowing this first, that no prophecy of scripture is of private interpretation. For no prophecy ever came by the will of man: but men spake from God, being moved by the Holy Spirit." — 2 Peter 1:20-21 (ASV)

Knowing this first, that no prophecy of the scripture 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.

How we do rejoice in this fact! We shall never give it up. It is a disbelief of inspiration, which lies at the bottom of all the modern theories; but with this disbelief we have not the slightest fellowship.

In our inmost souls we believe that holy men of God spake as they were moved (or, "borne along") by the Holy Ghost. They spoke not for their own age alone, neither were the prophecies given to a few persons so as to belong privately to them; but the whole inspired Scripture stands fast for all the faithful, and is the truth to us today, even as it was to those to whom it was first spoken.
