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. More certain for Peter, and for us who are the LORD’S, to which we do well to continue to hear and follow, is the prophecy [declaration] of the LORD Jesus that we have in the revealed, written, inspired word of God. This word is not an index of subjects, but ONE revelation, ONE united message, transcribed by ‘holy men,’ [sanctified by the Spirit], whose ONE subject is the LORD Jesus Christ. The revelation of Christ, through the word is described as the day star (Sun of Righteousness) shining in the heart. All is dark and obscure in our hearts because of sin until/unless the Spirit grants life to believe, and turn from sinful self-pleasing and self-righteousness to the only Righteousness that God the Father accepts, that which the LORD Jesus earned and established, and the Father imputed to the spiritual account of every one of His elect ones, once for all. No scripture is of any private interpretation. It is the Spirit who reveals Christ as they Word, and the One satisfaction of God for His people. Any other interpretation that is less than giving Christ ALL the glory is false.
