Clearly, Jesus is the speaker in Revelation 21:5, because it is he who sits upon the throne. He declares, “I make all things new,” but what does he mean by he makes all things new? Well, first of all, we may be assured that, as the Lord had done in the beginning (Genesis 1:1; John 1:1, 3), so it would do for the new creation (Revelation 21:5). In other words, God and only God could be responsible for making all things new. Just as mankind is unable to avoid death, neither could he resurrect himself. Notice what Paul says about the new creation:
For the love of Christ constrains us; because we thus judge, that if one died for all, then were all dead: And that he died for all, that they which live should not henceforth live unto themselves, but unto him which died for them, and rose again. Wherefore henceforth know we no man after the flesh: yea, though we have known Christ after the flesh, yet now henceforth know we him no more. Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. (2 Corinthians 5:14-17; emphasis mine)
Notice, first of all, that the new creation (v.17) is a spiritual matter. It has absolutely nothing to do with the destruction of the universe and God creating a new one, as so many futurists believe will occur. The new creation is found in and comes forth from Christ, just as it had been physically done in the beginning (John 1:1, 3). Secondly, notice that the death and resurrection of Christ have everything to do with the new creation. All were dead, because Christ died. In another epistle Paul concluded that the whole creation in the beginning came forth or was brought into existence through the One who became Jesus:
For by (G1722) Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities–all things have been created through (G1223) Him and for Him. He is before all things, and in (G1722) Him all things hold together. (Colossians 1:16-17; Strongs numbers inserted)
I could say that I created my family **in** (or by – G1722) my wife. Everything I had to do with my daughters being born was deposited **in** my wife. My daughters came into this world **through** (G1223) her. This is why the male alone is not the image of God, but both male and female, together, are the image of God (Genesis 1:27). The whole universe, including mankind, was created by the Father, but through his Son. All of creation was deposited **in** him and brought forth in maturity **through** him. The man **plus** the woman image this act of God.
Now consider this. If Christ, the very One who holds creation together (Colossians 1:17), died, what would have happened to that creation, which was held together by him? Wouldn’t it have started to become chaotic and begin to pass away? As Christ hung dying on the cross, what occurred in the heavens that he created (Matthew 27:45)? From noon until 3 PM (as we reckon time) the world became darker. How could that occur? It is impossible according to known laws of nature. Was it a unique miracle done by Christ, as he was on the cross? Or, were the ‘lights’ of the world growing dim, because the Light of the world was dying? I believe the latter is so. Notice, as well, when the ‘lights’ of the world began to return to normal. It was when Jesus cried out at the 9th hour (Matthew 27:46). At that very moment the lights of heaven began to brighten. It was when Christ called out to his Father: “Why have you forsaken me?” Had the Father forsaken his Son? How could that be? God could never deny himself (2Timothy 2:13), because God cannot be what God is not. He remains faithful always. The Scripture tells us that, while Christ hung dying on the cross, the Father was **in** him, not abandoning him, as so many Biblical scholars conclude. The Father was **in** Christ, reconciling the world to himself (2Corinthians 5:19). It is an impossibility for the Father to be abandoning Christ, while he (the Father) was **in** him. The doctrine of man that say the Father turned away from his Son simply doesn’t make sense.
So, why did Christ cry out? It was in reply to his enemies who had concluded and were causing others to believe that the Father had abandoned his Son (Matthew 27:39-44). Jesus used their own words against them to prove God hadn’t forsaken him. He judged the very lies that came from their own mouths (cp. Luke 19:22), proving he wasn’t forsaken, by reversing the darkness that had enveloped the land. It was because Christ prayed that the heavens grew brighter, and immediately afterward Christ placed his Spirit (and with his Spirit, the fate of the universe) into the hands of his Father (Luke 23:46).
So, what does this have to do with the one seated upon the throne making all things new (Revelation 21:5)? Men love to take one Scripture and imagine they know exactly what it says, but this cannot be done with the word of God. All things spiritual must be compared with other spiritual things (1Corinthians 2:13), because these matters are not naturally known by man (1Corinthians 2:9). Therefore, if man has so misunderstood what Jesus said upon the cross, because men haven’t compared Jesus words with Scripture found elsewhere, how could futurists conclude Jesus would destroy the physical creation and recreate a new universe simply from what he says in Revelation 21:5? Rather, this is covenantal language showing that the Old Covenant had passed away in the destruction of Jerusalem and the Temple, and Christ makes all things new by establishing the New Covenant. The New Covenant and the very existence of the universe depended upon Christ rising from the dead, and the establishment of that covenant / new creation depended upon his promise to return to destroy the Old Covenant (1Corinthians 7:31; Hebrews 8:13; 10:9; 1John 2:8, 17). Thus, in 70 AD he made all things new!
