A new Temple will have to have the same Commandment as the Moses and/or Dawid (Dowd) received by a Spritual Messenger (Yahs Salvation in Torah). The Temple that will be built next on Mount Moriyah will be a fraud. The one that The Messiah (Yahs Salvation) completes will be a Spiritural Temple in which His Saints will be The Columns. All who enter will have to be Spiritural (Spirit Filled) Yisraelites, no gates for gentile or Xtians, nor moslims. You do not have to be Hebrew to become a Spirit filled Yisraelite.
But Christ said that at His return that not one stone will be left atop another, a huge pile of sand. Christ is coming for a harvest and a cleansing.
