Among Christians there is great confusion about the NT temple concept. For example, there is no temple in heaven. As for the earthly temple, it's much closer than one thinks. Paul explains:
16 Do you not know that you are God's temple and that God's Spirit lives in you?
17 If someone destroys God's temple, God will destroy him. For God's temple is holy, which is what you are. (1 Cor. 3:16, 17)
16 And what mutual agreement does the temple of God have with idols? For we are the temple of the living God, just as God said, "I will live in them and will walk among them, and I will be their God, and they will be my people." (2 Cor. 6:16)
21 In him the whole building, being joined together, grows into a holy temple in the Lord,
22 in whom you also are being built together into a dwelling place of God in the Spirit. (Eph. 2:21-22; cf. 1 Pet. 2:4-9 NET)
