Matthew Henry Commentary Revelation 21:22-27

"And I saw no temple therein: for the Lord God the Almighty, and the Lamb, are the temple thereof. And the city hath no need of the sun, neither of the moon, to shine upon it: for the glory of God did lighten it, and the lamp thereof [is] the Lamb. And the nations shall walk amidst the light thereof: and the kings of the earth bring their glory into it. And the gates thereof shall in no wise be shut by day (for there shall be no night there): and they shall bring the glory and the honor of the nations into it: and there shall in no wise enter into it anything unclean, or he that maketh an abomination and a lie: but only they that are written in the Lamb`s book of life." — Revelation 21:22-27 (ASV)

Perfect and direct communion with God will more than replace gospel institutions. And what words can more fully express the union and co-equality of the Son with the Father in the Godhead? What a dismal world this would 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, there is no need of shutting the gates; all is at peace and secure. All this shows us that we should be increasingly led to think of heaven as filled with the glory of God and illuminated 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 those who 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.
