Some believers say that this desecration has already occurred before the Temple was destroyed in 70 A.D. However, double prophecies are known to co exists in scriptures and I believe that the Third Temple will be built as prophesied, and although I do not remember the exact reference in Daniel, it is prophesied that when they give the command out to build that third Temple, that would be the signal of the beginning of the 7 years Great Tribulation.
So yes, we, the believers, are God's Temple, but the Jews that believe not, will be the ones building that third Temple for the great tribulation.
A divided hope is an insecure hope and thereby lacking the necessary assurance for that singular hope to be hope.
Let nothing divide your hope in Jesus. Colossians 1:20-23
