The crucial point of the book of Nehemiah is that the city of Jerusaem was a safeguard and protection for the house of God, which was in the city. This signifies that the house of God as His dwelling place and home on the earth needs His kingdom to be established as a realm to safeguard His interest on the earth for His administraton, to carry out His economy. The rebuilding of the house of God typifies God's recovery of the degraded church, and the rebuilding of the wall of the city of Jerusalem typifies God's recovery of His kingdom. God's building of His house and His building of His kingdom go together. The house of God on the earth needs His kingdom to safeguard the house and to carry out His eternal economy.
