2 Peter 1:19.
The prophecies are the key.
Although
---they are intended to be understood by those of us who, by the study of them, understand that we live in the last days.
The apostle John himself may have understood little contained in the Revelation, yet by inspiration he declared, "Blessed is he that reads, and they that bear the words of this prophecy." Rev. 1:3."
