Revelation 21:5
He who sat on the throne said
This is God the Father Who John saw when he first ascended in his vision to heaven (Rev. Rev. 4:2+, Rev. 4:9+; Rev. 5:1+).

Behold, I make all things new.
I make is ποιῶ [poiō] , present tense: I am making. New is καινὰ [kaina] , new in quality or kind, better. See commentary on Revelation 21:1. What God creates in the new heaven and new earth will surpass anything which man has imagined: “But as it is written: ‘Eye has not seen, nor ear heard, nor have entered into the heart of man the things which God has prepared for those who love Him.’ ” (1Cor. 1Cor. 2:9 cf. Isa. Isa. 43:16-19). The old creation which had long groaned under corruption is delivered by a new creation:

For the earnest expectation of the creation eagerly waits for the revealing of the sons of God. For the creation was subjected to futility, not willingly, but because of Him who subjected it in hope; because the creation itself also will be delivered from the bondage of corruption into the glorious liberty of the children of God. For we know that the whole creation groans and labors with birth pangs together until now. Not only that, but we also who have the firstfruits of the Spirit, even we ourselves groan within ourselves, eagerly waiting for the adoption, the redemption of our body. (Rom. Rom. 8:19-23)

The redemption set forth in the book of Revelation is much broader than the individual redemption of sinful men. It extends to the redemption of the earth and even the entire creation. See commentary on Revelation 5:1. Like the new birth, the new creation is a work of God: “Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new” (2Cor. 2Cor. 5:17).

Write, for these words are true and faithful
John is reminded of his task, to record that which he sees and hears for the benefit of the saints. See commentary on Revelation 1:11 and Revelation 1:19. The statements which God has just made, concerning the elimination of death and the making of all things new, are difficult for people living under the dominion of physical death to consider so God emphasizes the reliability of what John has been told (Rev. Rev. 19:9+; Rev. 22:6+). “Forever, O LORD, your word is settled in heaven” (Ps. Ps. 119:89). The word of God lives and abides forever (1Pe. 1Pe. 1:23). The words spoken by the voice from heaven have the same characteristics as those of Jesus. Jesus referred to Himself as “the Amen, the Faithful and True Witness” (Rev. Rev. 3:14+). When He rode forth at the Second Coming, He was called “Faithful and True . . . the Word of God” (Rev. Rev. 19:11-13+). There is unity between the will of the Father and the Son.
