Some how, some way, this thing has got to go.
I don't know how, but it will. Perhaps it will be destroyed in an earthquake. Maybe it will collapse all on its own due to recent excavation by the Muslims near its base. It could be destroyed during a war or battle. But it has got to go so that the Third Temple can be rebuilt.
Jerusalem isn't even mentioned in Qu'ran (or Koran, or however they want to spell it this month).
The Muslims basically squatted and built the Dome of the Rock (AD 691) and the Al Aqsa mosque (AD 705) on the Temple Mount to spite the Jewish people and to spite God, pure and simple. The Dome was also built specifically as an "in your face" to Christians and to the Messiah as well.
Jerusalem's Dome of the Rock is Hate Speech in Stone; Its removal Urgent
"The LORD will roar from Zion and thunder from Jerusalem; the earth and the sky will tremble. But the LORD will be a refuge for his people, a stronghold for the people of Israel. 'Then you will know that I, the LORD your God, dwell in Zion, my holy hill. Jerusalem will be holy; never again will foreigners invade her.'" (Joel 3:16-17)
I just hope it happens in my lifetime!
God will take it down just like He did with the walls of Jericho. All in His due time. IF the Israelis just go and do it, it will likely be the event that starts WWIII.
BTW, not only are they training priests etc., they also have the plans, equipment and materials already in place to start construction.
