There is a spiritual temple that true believers compose and then there is the physical temple that God commands Israel to build. They serve different purposes. The physical and spiritual temples complement one another, they do not compete against each other.
King David and the Prophets had the Holy Spirit. They were the spiritual tabernacle/temple in their days, but it didn't stop their great respect and understanding that the physical temple in Jerusalem had its God-ordained purpose, such as a place for the nation to worship together, and a place for foreigners to come and worship the God of Jacob. God commands Israel to build His House of Prayer for All Peoples to again serve that transcendent purpose. Will Israel soon fulfill their calling to do so?
