2 Peter 1:16-21
16 For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty.
17 For he received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased.
18 And this voice which came from heaven we heard, when we were with him in the holy mount.
19 We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts:
20 Knowing this first, that no prophecy of the scripture is of any private interpretation.
21 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.
-In verse 18, Peter references his experience watching Jesus on the mount of transfiguration. During that experience, the voice of God the Father could be heard saying, “This is my beloved Son: hear him.” (Luke 9:35) In verse 19, Peter tells us that even in light of that experience, there is a more sure word and that is the Word of God. The inspired, written Word of God is “a more sure word” than the audible voice of God heard on the mount of transfiguration! For the Word is not of men, but of the Holy Ghost (v.21) and God has magnified His Word above even His name. (Psalm 138:2)
