And there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb's book of life.

People's New Testament

21:27 There shall in no wise enter into it any thing that defileth. Nothing sinful or unclean shall ever enter, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb's book of life.

Wesley's Notes

21:27 Common - That is. unholy. But those who are written in the Lamb's book of life - True, holy, persevering believers. This blessedness is enjoyed by those only; and, as such, they are registered among them who are to inherit eternal life.

Jamieson-Fausset-Brown Bible Commentary

27. anything that defileth-Greek, "koinoun." A and B read [koinon,] "anything unclean."

in the Lamb's book of life-(See on [2745]Re 20:12; [2746]Re 20:15). As all the filth of the old Jerusalem was carried outside the walls and burnt there, so nothing defiled shall enter the heavenly city, but be burnt outside (compare Re 22:15). It is striking that the apostle of love, who shows us the glories of the heavenly city, is he also who speaks most plainly of the terrors of hell. On Re 21:26, 27, Alford writes a Note, rash in speculation, about the heathen nations, above what is written, and not at all required by the sacred text: compare Note, see on [2747]Re 21:26.

Matthew Henry's Concise Commentary

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.
