I wish I was kidding but I'm not.
I'm a Catholic but I can expand on this.
The evangelicals believe that the Third Temple must be built for the Second Coming of Christ to happen, and are determined to politically and financially support the nation of Israel to make it happen as soon as possible.
They also actively work torwards the destruction of al-Aqsa Mosque and the rebuilding of the 3rd Temple.
This belief comes form 2 Thessalonians:
"Now concerning the coming of our Lord Jesus Christ and our being gathered together to him, we ask you, brothers, not to be quickly shaken in mind or alarmed, either by a spirit or a spoken word, or a letter seeming to be from us, to the effect that the day of the Lord has come. Let no one deceive you in any way. For that day will not come, unless the rebellion comes first, and the man of lawlessness is revealed, the son of destruction, who opposes and exalts himself against every so-called god or object of worship, so that he takes his seat in the temple of God, proclaiming himself to be God."
The Church Fathers were unanimous on agreeing that the "Son of Destruction" was the anti-Christ, and while there was some disagreance over what St. Paul meant (in Galatians 6:15-16) by temple the majority consensus was that it was referring to the eartly Temple. But, as it stands, the Second Temple was shortly destroyed. Which means that in order for the Second Coming to happen again, the Temple will once again need to stand.
Both Catholics and Protestants are Christians but this is a major area of disagreement between us.
Not only is it real, but many people in Trump's administration have openly talked about this and how they want to make it happen.
Isn't there also some shit about a cow?
The scofield bible preaches accelerating/ triggering the rapture
Maybe you don't see it because you aren't willing to think this darkly. Rebuilding the Temple is not a particularly popular idea, either domestically in Israel or internationally. The country would have to be much further radicalized for that to become realistic. Executing an ethnic cleansing of their Arab population with the tacit endorsement of the US would arguably be steps along that path to creating a world in which the Third Temple might be built.
