Already built from followers of the Way. 1 Cor 3.
I’m a dispensationalist.
I believe the Temple will be rebuilt in God’s perfect will. It will not theologically replace Jesus.
“For these are the two covenants: the one from Mount Sinai which gives birth to bondage, which is Hagar— for this Hagar is Mount Sinai in Arabia, and corresponds to Jerusalem which now is, and is in bondage with her children— but the Jerusalem above is free, which is the mother of us all.” (Galatians 4)
Pray that those in bondage in Jerusalem would have their spiritual eyes opened to the true Israel of God, Jesus Christ.
