For instance, it it claimed that the "future Antichrist dude" is going to sit in a rebuilt "temple of God", but they fail to take into account that Paul refers to the church over and over as the "temple" (Gr. "Naos"). Furthermore, it is unbelievably naive to think that God would refer to a rebuilt temple in Jerusalem as His temple...would God really inspire Paul to use "temple of God" to refer to a building
God inspired Matthew to say it ...Matthew 21:12 And Jesus entered into the
temple of
God, and did cast forth all those selling and
buying in the
temple, and the tables of the money-changers (if you are thinking, only because it was before the cross, remember Matthew is writing after the cross. Using this phrase did not mean Matthew was suggesting that the temple was not replaced by the Cross. Your logic is flawed your case does not stand.)
Acts 8:38 enter with them into the
temple, walking and springing, and praising
God (the first church being the temple of God were meeting in the temple that we know was nothing more than a convenient meeting place for 3000 new converts, but nevertheless they still referred to it as the temple..)
Luke 24:53 (Luke traveled with Paul and ends his book with)... and were continually in the
temple, praising and blessing
God.
So yes! Since Paul was referring to prophecies of Daniel he meant exactly the temple standing when he was writing not knowing that it would be destroyed in 70AD he was nevertheless interpreting the prophecies of Daniel as referring to the only temple of God that the people who read it would understand. They all knew he was talking about the Jewish Temple. If he meant the believers body he would have made that clear, by saying something in the immediate context like, you are the temple of God and then everyone would get that, but not saying that the more natural interpretation is that he is interpreting Daniels prophesy as that Man of Sin standing in the Holy Place in the temple, which of course would require that it be rebuilt.
We read commentaries from a few hundred years ago that state a belief in a restoration of the nation of Israel and a rebuilt temple. Those authors were mocked by those that said God had replaced Israel with the church and there will be no restoration of the nation. They don't say that anymore. Soon that temple will be rebuilt and the mockers will say it means nothing and then the Man of Sin will be revealed and still they will say it is all something other than what Paul was talking about.
For me this one is not that difficult to decide. The Mark is a mystery but it will probably be pretty much exactly what it says as well. A literal physical brand, official seal.
