Isaiah 33:20
Look upon Zion, the city of our solemnities: thine eyes shall see Jerusalem a quiet habitation, a tabernacle that shall not be taken down; not one of the stakes thereof shall ever be removed, neither shall any of the cords thereof be broken.
Zion is the city of appointed worship gatherings, the place of worship toward which God's people press on their way to God's throne. Jerusalem to be seen is a quiet habitation, a calm, peaceful and secure dwelling that will endure and never be taken down, moved, or dismantled, with not one of its stakes ever removed nor any of its cords broken. In the promised reign of salvation the Lord dwells and reigns there as judge, lawgiver and king, bringing salvation to His people.
It is a lasting home for God's people where sin is forgiven, sickness is absent, and there is joy and freedom from suffering. This stable habitation belongs to a spiritual picture of Christ's kingdom, whose government reflects the holy love, charity, pity and lovingkindness of its people. The tabernacle that shall never be taken down is the Holy City when situated on the new earth, which alone will then be God's tabernacle and temple.
Applied to present truth, the tent that cannot be dismantled means the truths God has established are firm foundations, and not one part of them is to be removed. Applied to unity, the cords that hold Zion together must not be weakened or broken by belittling the efforts of fellow workers simply because they do not meet one's own ideas. Such belittling ideas are often out of harmony with the mind and will of God, and only a changed, pure and unselfish character that hides self in Jesus and is fully imbued with the spirit of truth will keep a person from doing that harm.
