It is not that prophecy has some deep, hidden, mysterious meaning that so many fail to understand it. The apostle Peter has said of it, “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.” 292 Peter 1:20, 21 It is plainly implied from this language that what is essential to an understanding of prophecy is the reception of that spirit which spake through the prophets. Of that spirit, promised to all who seek it, it is written, “He will guide you into all truth.” 30John 16:13 GSAM 30.1
