The born again believer's body that has the Holy Spirit dwelling inside of them is called the temple of the Holy Spirit or the temple of God according to 1 Corinthians 3:16-17, and 2 Corinthians 6:17. So I can't see Satan dwelling inside the body of a born again believer with the Holy Spirit already dwelling there. Besides 2 Thess. 2:3-4 says the son of perdition as God sitteth in the temple of God showing himself that he is God. If the son of perdition is human and possessed by Satan, how can he possibly sit inside each born again believer's body which is the temple of God? I didn't think that he could.
In regard to a literal temple of God being rebuilt in Jerusalem on Earth, there is no need for it to be rebuilt because our Lord Jesus Christ was the sacrifice on the cross for the sins of the world so us born again believers wouldn't rebuild the temple of God in Jerusalem so that animals could be sacrificed for our sins. However, since the Jewish people don't believe that Jesus Christ was the Messiah nor do they believe that He died on the cross for their sins, they want to rebuild the temple and begin sacrificing animals again for their sins as instructed in the laws of Moses. As you know, the Temple Institute is preparing to do so. So they can rebuild the temple in Jerusalem, and it could look like the temple of God, and it could be called the temple of God by them, but the Lord God is not going to accept the daily animal sacrifices for their sins although they may mistakenly believe that God will. So I can see the temple being rebuilt in Jerusalem as a man made effort.
2 Thessalonians 2:3-4 tells us that the man of sin, the son of perdition as God sitteth in the temple of God, showing himself that he is God. Where in the temple in Jerusalem could the son of perdition as God sit showing himself that he is God? Where was the glory and the holy presence of the real Lord God Yahweh in the temple of God in Jerusalem? His shekinah glory was over the mercy seat in the Holy of Holies where the high priest could only enter once a year on the day of atonement ( Yom Kippur) with animal blood for the high priest's sins and for the sins of the people according to Hebrews 9:7. The high priest had bells sewn on the bottom of his garment so that they could hear him moving around inside of the Holy of Holies which meant he was alive, and there also was a rope tied around his ankle to pull him out if he dropped dead while he was in there. So if the son of perdition was to enter the Holy of Holies and sit on God's mercy seat, and didn't drop dead, wouldn't he show himself that he was God by sitting there, and could this possibly be part of the great delusion to make others believe that he is God? I honestly don't think that the real God's glory and presence is going to be over the mercy seat inside the Holy of Holies in the temple that the son of perdition sitteth in since the real God no longer accepts the blood of a sacrificed animal for the sins of the people. So this would give the son of perdition an opportunity to seat himself there as God to show himself that he is God and it would also fool others into believing that the son of perdition is God if he should sit on the mercy seat and remain alive.
It also makes me wonder if the son of perdition will possibly take blood from his deadly wound that was healed to place on the mercy seat as a make believe offering for the sins of the people to fool them into believing he is God as their savior and messiah.
I also wonder if the image of the beast which should speak according to Rev. 13:15 is the abomination of desolation that will stand in the holy place in Matthew 24:15 and that is set up according to Daniel 12:11.
These are just some things to ponder. There is also a temple of God up in heaven according to Rev. 11:19, 14:15, 14:17, 15:5, 15:6, 15:8, 16:1 and 16:17. Rev. 15:8 says, "And the temple was filled with smoke from the glory of God, and from his power; and no man was able to enter into the temple, till the seven plagues of the seven angels were fulfilled." However, in speaking about the city of New Jerusalem, Rev. 21:22 says, "And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it."
