Well, wherever it is rebuilt, we’ve got our work clearly defined for us.
I still don’t know how the Jews intend to reinstitute the sacrifices that were a primary reason for that style of temple worship in Jerusalem.
Of course, born-again believers in Lord Jesus Christ know that we the church are the temple of God with Christ as the head of His body of believers and that His personal sacrifice (The Cross) completely finished God’s plan of redemption once and for all time, negating the need for another building in Jerusalem other than the one He has built with His own hand.
I long to see the Day that all Israel (including Judah) believe that.
