Revelation 21:5 (ESV) … “And he who was seated on the throne said, “Behold, I am making all things new.” Also he said, “Write this down, for these words are trustworthy and true.”
For the second time in Revelation, God himself is the speaker. We heard Him earlier in Revelation 1:8 when He tells us, “I am the Alpha and the Omega,” says the Lord God, “who is and who was and who is to come, the Almighty.” So, we have no doubt to the promise about to be given to us in Revelation 21:5.
Revelation 21:5 is a strong confirmation that God’s power will be revealed, and his redemptive purposes finally and entirely fulfilled. Since these words are in truth God’s words, it is of utmost importance that this vision of the new heaven and the New Jerusalem be proclaimed to the church.
When we read this verse, we must understand that these blessed promises of glory to come are here assured to us by the oath of Him who is ‘faithful and true.’ The oath of our Savior says, ‘Behold, I make all things new!’
D.S. Fortner tells us in his book, Discovering Christ in Revelation, that the language in verse 5 is in the present tense. That Christ is now making all things new by His providence and grace (Rom. 8:28; 11:36; 2 Cor. 5:17). Soon his work will be done. When that great day comes, he will declare, ‘It is done!’ All that was purposed and planned by God the Father before the world began, all that Christ agreed to as our surety in the everlasting covenant, all that He came into this world to accomplish, will be done when time is no more.

This oath and promise is that God’s works will be finished exactly as He purposed. Everything that has been now or will be in the future will serve His glorious purpose and ultimately glorify Him. Everything, in the end, will prove to have been the work of God for the salvation of His people. It is written: ‘All things are of God’ (2 Cor. 5:18). And when our dear Savior has made all things new, when the triune God has finished his work, we shall see that it has been so (Rom. 8:28–30).
