I and many other Christians believe that the temple must be rebuilt before the Tribulation because of (Daniel 9:27), saying that there will be "an end to sacrifice and offering", which implies the temple is present and rebuilt once again.

If you've been following Israel news, you'll see there's been much talk as of recent about rebuilding the temple. The link I shared from the Jerusalem Post, a very prominent and reputable news organization, goes in depth about this from a Christian perspective. I wanted to share this article with everyone because obviously the rebuilding of the temple is of big significance in end times prophecy.

There's no denying that there's an active effort being pushed for preparations to rebuild the temple. An example of this would be the search for a real red heiferin order to fulfill the command the Lord gave to Moses (Numbers 19:1–10) to make the waters of purification.

Something I also found interesting what this following excerpt,

"There’s a very important prophecy by the apostle Paul in Second Thessalonians 2:4, “He [the man of lawlessness] will oppose and will exalt himself over everything that is called God or is worshiped, so that he sets himself up in God’s Temple, proclaiming himself to be God.”

Christian Bible prophecy scholars say that only a man of diplomatic skill who will be accepted by both Jews and Muslims will be able to broker a plan that would allow the Jewish people to worship in a Temple on the Mount where King David originally purchased territory. But many Christian eschatologists warn that Daniel 9:27 predicts that this deal maker, better known as the antichrist, will break the peace plan. Isaiah 28:18 reportedly calls it a “covenant with death” that will be annulled."

This means the antichrist, or the man of lawlessness, will be of, or rise to, a degree of prominence and influence to be able to negotiate between both sides. It has to be someone both Jews and Muslims look on at least somewhat positively on.
