I believe that Jesus body IS the third temple and the saints are a part of Jesus body who make up the temple too. Here are some verses which explain why.
John 2:19 On account of this, the Jews demanded, “What sign can You (Jesus) show us to prove Your authority to do these things?” 19 Jesus answered, “Destroy this temple and in three days I will raise it up again.” 20“This temple took forty-six years to build,” the Jews replied, “and You are going to raise it up in three days?”… But Jesus was speaking about the TEMPLE of His BODY…
Acts 7: 45 And our fathers who received it (The Tabernacle of Witness) brought it in with Joshua when they dispossessed the nations God drove out before them. It remained until the time of David, 46 who found favour in the sight of God and asked to provide a dwelling place for the GOD of Jacob. 47 But it was Solomon who built the house for Him…. Acts 7:48 However, the Most High does NOT LIVE IN HOUSES MADE BY HUMAN HANDS. As the prophet says: 49 ‘Heaven is My throne and the earth is My footstool. What kind of house will you build for Me, says the Lord, or where will My place of repose be? 50 Has not My hand made all these things?
Jesus has no building to reside in here on earth now, other than the TEMPLE/BUILDING made up of believers – made with HIS HANDS.
Ephesians 2:19-22 So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God’s household, having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone, in whom the WHOLE BUILDING, being fitted together, is growing into a HOLY TEMPLE IN THE LORD, in whom you also are being built together into a DWELLING OF GOD in the Spirit.
1 Corinthians 3:16 Do you not know that YOU ARE THE TEMPLE God and that the Spirit of God dwells in you?
2 Corinthians 6:16 For YOU ARE THE TEMPLE of the living God; as God has said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.
So what does the Man of Lawlessness appear like, if the temple is not a temple built with hands?
2 Corinthians 6: 14-18 Do not be bound together with unbelievers; for what partnership have righteousness and LAWLESSNESS or what fellowship has light with darkness? Or what harmony has Christ with Belial, or what has a believer in common with an unbeliever? Or what agreement has the TEMPLE OF GOD with “IDOLS”? For WE ARE THE TEMPLE of the living God; just as God said, “I WILL DWELL IN THEM AND WALK AMONG THEM; AND I WILL BE THEIR GOD, AND THEY SHALL BE MY PEOPLE
2 Thessalonians 2 Concerning the coming of our Lord Jesus Christ and our being gathered to him, we ask you, brothers and sisters, that you not be quickly shaken from your composure or be disturbed either by a spirit or a message or a letter as if from us, to the effect that the day of the Lord has come. 3 Let no one in any way deceive you, for it will not come unless the apostasy comes first, and the man of LAWESSNESS (unbeliever) is revealed, the son of destruction, 4.who opposes and exalts himself above every so-called god or object of worship, so that he takes his SEAT in the TEMPLE OF GOD, displaying himself AS BEING GOD.
So I divulge from these verses that the ‘Man of Lawlessness’ is not found in a man-made Jewish temple in Jerusalem, but rather is an unbeliever (as 2 Cor 14-18 specifically explains Lawlessness as an unbeliever and someone that is Idolized….) who sets himself up as ‘God’ in the ‘temple of believers‘.
