I’m afraid most don’t understand that. I’ve heard Christians clamor for a new temple my whole life. I bet you have, too. If there’s a push to build a new temple, Christians should have nothing to do with it because it won’t honor Christ. What need does a believer have of renewed temple sacrifices?
Perhaps you missed the part where Christ Himself talks about the temple being desecrated in the future tense?
When folks start hearing this kind of talk it should make Christians all over the world rejoice because Prophecy is being fulfilled. When it does happen (and it will), it’s one major step closer towards His soon return. And the way things are ramping up these days, He might even return before the first brick is laid.
If you don’t believe in Dispensationalism, then this whole discussion is moot. It’s exactly why Christians clamor for a new temple.
It is a precursor to the Return of Christ.
