The reason of Jerusalem's peace, security and prosperity will be the glory of the Lord. This glory will be in the midst of the city, and will also form a wall of fire around the city. For I, saith the Lord, will be unto her a wall of fire round about the city, and I will be the glory in the midst of her. Glory and defence are here combined. They always go together. This has been in a degree already the happy lot of Israel in the past, for He guided them with His glory. It was a cloud by day and a fire at night by which the Lord had revealed Himself to His people, and out of that glory cloud He protected them and punished their enemies. How much greater will that glory and defence be in that time of fullness when Israel is no longer a disobedient, stiff-necked people, but the holy people, the kingly nation. What a glory that will be when the King comes back with His kingly glory, attended by the many, many brethren who have suffered with Him and now share His glory! What a glory that will be when He, who is our life, will be manifested, and we with Him in His glory! It will be unspeakable glory. Cry aloud and shout thou inhabitant of Zion, for great is the Holy One of Israel in the midst of thee. And it shall come to pass, that He that is left in Zion and he that remaineth in Jerusalem shall be called holy, even every one that is written among the living in Jerusalem when the Lord shall have washed away the filth of the daughters of Zion, and shall have purged the blood of Jerusalem from the midst thereof by the blast of judgment and burning. And the Lord will create over the whole habitation of Mount Zion and over her assemblies a cloud and smoke by day, and the shining of a flaming fire by night, for over all the glory shall be spread a canopy. There shall be a pavilion for a shadow in the day time from the heat, and for a refuge and for a covert from storm and from rain. (Isaiah iv.) This glory during the Millennium will no doubt not only hover over the land, but will be visible over the entire earth, and the knowledge of the glory of the Lord will cover the earth as the waters the sea.
