What did the Old Testament prophesy about the Kingdom?
The Old Testament prophesied the coming of the King and the Kingdom, when Israel shall reign gloriously. It spoke of this Kingdom as forever, indicating it is eternal. However, the Old Testament did not attach a time frame to it; that specific thousand-year period first appears in Revelation.
Les explains that the Kingdom has been spoken of and prophesied all the way through the Old Testament—the coming of the King and the Kingdom, when Israel shall reign gloriously. The Old Testament speaks of it as forever, showing the Kingdom is eternal. Only in Revelation is a time frame attached: a thousand years. This follows the seven-year tribulation, when Christ returns, destroys the remaining armies and those still in rebellion, and the earth is brought back to an Eden-like condition before the thousand years begin.
