Deception has entered into the body of Christ. Many believe that a temple must be built on the Temple Mount in Jerusalem so and that the antichrist will set himself up there, and then break a seven-year treaty with Israel.
This viewed is flawed and has been the cause of other prophecy interpretations becoming skewed.
No New Testament prophet ever said there would ever be another temple built. Jesus fulfilled the law and we as His followers are now temples. Paul, who gave the antichrist prophecy being setup in a temple was talking about us, Believers, and the Church in general.
All of this is explained in the book Abomination of Desolation.
