Not sure I understand what you are asking about something being totally separate. The subject was about the strong delusion. The beast will try to imitate God in the temple, and sacrifices will cease and he will set up an abomination. Then, the subject somehow got switched to us being the temple -- I've even heard stories that this abomination meant the corruption of Christians. While that's the spiritual counterpart that we are His temple, that does not eliminate the fact that a physical one will be reconstructed, and indeed one by Christ himself when he returns, and the whole Levitical system started up again as explained in the end of the book of Ezekiel. That's not for us or our sake. That's for those in the millennium under the perfect government of God. Christians (i.e. the church) are the spiritual counterpart if you will of the tribes of Judah and Levi, just as they physically ruled and were priests for the rest of Israel, likewise the resurrected saints will do the same for those in the flesh yet of Israel, and indeed, the whole world. In other words, our lot is to rule and teach the world his Law. Not "die and go to heaven". I don't even go there in my theology. It's coming to earth, and we start when we are raised again at his coming.
