21:24 The nations of them which are saved shall walk in the light of it. The redeemed of all nations enjoy the light of the city.
And the kings of the earth do bring their glory and honour into it. The idea is that all who have earthly dignities and honors shall make them offerings to the New Jerusalem.
21:24 And the nations - The whole verse is taken from Isaiah 60:3. Shall walk by the light thereof - Which throws itself outward from the city far and near. And the kings of the earth - Those of them who have a part there. Bring their glory into it - Not their old glory, which is now abolished; but such as becomes the new earth, and receives an immense addition by their entrance into the city.
21:22-27 Perfect and direct communion with God, will more than supply the place of gospel institutions. And what words can more full express the union and co-equality of the Son with the Father, in the Godhead? What a dismal world would this be, if it were not for the light of the sun! What is there in heaven that supplies its place? The glory of God lightens that city, and the Lamb is the Light thereof. God in Christ will be an everlasting Fountain of knowledge and joy to the saints in heaven. There is no night, therefore no need of shutting the gates; all is at peace and secure. The whole shows us that we should be more and more led to think of heaven as filled with the glory of God, and enlightened by the presence of the Lord Jesus. Nothing sinful or unclean, idolatrous, or false and deceitful, can enter. All the inhabitants are made perfect in holiness. Now the saints feel a sad mixture of corruption, which hinders them in the service of God, and interrupts their communion with him; but, at their entrance into the holy of holies, they are washed in the laver of Christ's blood, and presented to the Father without spot. None are admitted into heaven who work abominations. It is free from hypocrites, such as make lies. As nothing unclean can enter heaven, let us be stirred up by these glimpses of heavenly things, to use all diligence, and to perfect holiness in the fear of God.
