"I'm not Dan58, but..."
'the temple'
Actually, the Temple mount. Although I believe a Temple will be erected, it does not have to be. You can read the story, it is the account of David numbering Israel (he was actually numbering his army) and God punished him for his lack of faith. We'll pick it up midstream...
1Ch 21:16 And David lifted up his eyes, and saw the angel of the LORD stand between the earth and the heaven, having a drawn sword in his hand stretched out over Jerusalem. Then David and the elders of Israel, who were clothed in sackcloth, fell upon their faces.
1Ch 21:17 And David said unto God, Is it not I that commanded the people to be numbered? even I it is that have sinned and done evil indeed; but as for these sheep, what have they done? let thine hand, I pray thee, O LORD my God, be on me, and on my father's house; but not on thy people, that they should be plagued.
1Ch 21:18 Then the angel of the LORD commanded Gad to say to David, that David should go up, and set up an altar unto the LORD in the threshingfloor of Ornan the Jebusite.
Notice that God picked the location...
1Ch 21:22 Then David said to Ornan, Grant me the place of this threshingfloor, that I may build an altar therein unto the LORD: thou shalt grant it me for the full price: that the plague may be stayed from the people.
1Ch 21:23 And Ornan said unto David, Take it to thee, and let my lord the king do that which is good in his eyes: lo, I give thee the oxen also for burnt offerings, and the threshing instruments for wood, and the wheat for the meat offering; I give it all.
1Ch 21:24 And king David said to Ornan, Nay; but I will verily buy it for the full price: for I will not take that which is thine for the LORD, nor offer burnt offerings without cost.
1Ch 21:25 So David gave to Ornan for the place six hundred shekels of gold by weight.
1Ch 21:26 And David
built there an altar unto the LORD, and offered burnt offerings and peace offerings, and called upon the LORD; and
he answered him from heaven by fire upon the altar of burnt offering.
So David erected a simple altar of uncut stones and offered the oxen he had bought and God accepted the offering DRAMATICALLY.
Now let's continue...
1Ch 21:27 And the LORD commanded the angel; and he put up his sword again into the sheath thereof.
1Ch 21:28 At that time when David saw that the LORD had answered him in the threshingfloor of Ornan the Jebusite, then he sacrificed there.
1Ch 21:29 For the tabernacle of the LORD, which Moses made in the wilderness,
and the altar of the burnt offering, were at that season in the high place at Gibeon.
Not on Mt Moriah, the Temple Mount, but rather at another location: Gibeon.
Now what comes next?
1Ch 22:1 Then David said, This is the house of the LORD God, and this is the altar of the burnt offering for Israel.
And not a foundational stone had been laid yet. God already viewed this location, the Temple Mount as the house of God.
Does there need to be an edifice erected for the Abomination of Desolation to take place? No.
Will it likely be? I think so.
