true.
but the temple has not been clean since the first temple was destroyed.
do you honestly think the high priest who had jesus killed actually entered the holy of holy's clean? No high priest had entered clean since even the babylonian return from exhile. Which proved Gods presence was never in it/.
remember, They had to tie a rope to the high priest, because if he was not clean he would die. How many unclean high priests entered and did not die, Gods presence left long before the babylonian captivity, and it never returned.
And again, They are trying to buld a temple today, if they would start, they would have it finished in less than a year. and they have ALL the stuff which is supposed to go in it already, including the animals, which they are raising up, and priests. (including the garments as required by the law of moses)
