Then how the heck is there a holy place where an abomination takes place if it’s religious Jews behind it?
The Holy place is the unseen place as God's hidden glory the place of faith. You could say he is our hiding place.
It will be the light of the glory of God of the new creation . The temporal time keepers no longer needed.
If we would apply it to the earthly Jerusalem as set aside as holy as the temporal, it again points to the eternal Holy Place.
Even the son of man, Jesus who informs us his of temporal flesh profits for nothing. He refused to recognized as in the Holy place . But when called good master he gave glory to God in the Holy place saying only God (not seen is good)
Good is defined in respect to God who has no form.
As a example the Catholics for one have filled that Holy place with 3500 and rising what they must call patron saints and the scripture calls workers with familiar spirits .
is a handy tool for seeing into the Holy place
While we look not at the things which are seen, but at the things which are not seen: for
the things which are seen are temporal; but the
things which are not seen are eternal.2 Corinithians 4:18
