Jerusalem is builded as a city that is compact together. David saw in vision the city built; no more a waste, or a mere collection of tents, or a city upon paper, commenced but not completed. God's mercy to the Israelitish nation allowed of peace and plenty, sufficient for the uprise and perfecting of its capital: that City flourished in happy times, even as the church is only built up when all the people of God are prospering. Thanks be to God, Jerusalem is builded: the Lord by his glorious appearing has built up Zion. Furthermore, it is not erected as a set of booths, or a conglomeration of hovels, but as a city, substantial, architectural, designed, arranged, and defended. The church is a permanent and important institution, founded on a rock, builded with art, and arranged with wisdom. The city of God had this peculiarity about it, that it was not a long, straggling street, or a city of magnificent distances (as some mere skeleton places have been styled), but the allotted space was filled, the buildings were a solid block, a massive unity: this struck the dwellers in villages, and conveyed to them the idea of close neighbourhood, sure standing, and strong defence. No quarter could be surprised and sacked while other portions of the town were unaware of the assault: the ramparts surrounded every part of the metropolis, which was singularly one and indivisible. There was no flaw in this diamond of the world, this pearl of cities. In a church one of the most delightful conditions is the compactness of unity: "one Lord, one faith, one baptism." A church should be one in creed and one in heart, one in testimony and one in service, one in aspiration and one in sympathy. They greatly injure our Jerusalem who would build dividing walls within her; she needs compacting, not dividing. There is no joy in going up to a church which is rent with internal dissension: the gladness of holy men is aroused by the adhesiveness of love, the unity of life; it would be their sadness if they saw the church to be a house divided against itself. Some bodies of Christians appear to be periodically blown to fragments, and no gracious man is glad to be in the way when the explosions take place: thither the tribes do not go up, for strife and contention are not attractive forces.
