Revelation 21:5: And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful.

In Revelation 21:3, the voice of God the Father announced from heaven that his Son, the tabernacle of God, is with men.¹ These words symbolically describe Christ's future reign on the celestial earth.² Therefore, in Revelation 21:5, Christ is he that sat upon the throne³ and John hears his voice again.⁴ This interpretation is also confirmed by Revelation 20:11, where John saw Christ sitting on the same throne during the final judgment of all sons of perdition.⁵ Additionally, Christ descends with the same throne to rule on the resurrected earth when the celestial city of New Jerusalem comes down from God out of heaven in Revelation 21:2.⁶

From his throne on this celestial earth, Christ declares: Behold, I make all things new.⁷ Christ confirms his identity as the maker of this promise by referring to himself as Alpha and Omega, the beginning and the end in the very next verse.⁸ Christ's promise to make all things new pertains to the newness of life⁹ that comes to all things through his life-giving atonement.¹⁰ The promise of new life extends to exaltation-worthy saints that will reign with Christ in the celestial kingdom.¹¹ It extends to unexalted people in the celestial kingdom,¹² and to all animals and plants resurrected to celestial glory.¹³ Finally, the promise of new life extends to the earth itself that will become a new heaven and new earth through the power of Christ's atonement.¹⁴

To signify the certainty and truth of Christ's prophetic promise to all things, John was commanded to write the promise¹⁵ so that none would miss the message or ever forget the promise.¹⁶ The Savior also confirms the promise with an oath in his own name,¹⁷ saying, these words are true and faithful.¹⁸ The certainty of the promise is hereby assured because it is given by the one and only person of this earth who is qualified to have the name and title of True and Faithful.¹⁹ Therefore, the words of Christ are unalterably true and given with absolute certainty.²⁰ His words are faithful in the sense that all will be fulfilled²¹ with complete fidelity.²² Christ's words are the promise of eternal life given to those worthy of this blessing.²³ The blessing of eternal life is the greatest of all the gifts of God.²⁴

Revelation 21:6: And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.

The Savior was still speaking when he said unto [John], It is done. This means that all the words of the prophets²⁵ concerning Christ's promises have come to pass.²⁶ The atonement was complete when Christ said it is finished from the cross at Calvary,²⁷ but his full redemptive work is done when Christ also makes all things new.²⁸ This outcome is so certain to occur in the future that when Christ spoke to John in 96 AD and said it is done in the present tense, it was as though all things had already been made new.²⁹

Christ confirms again that he is the speaker in Revelation 21:5-6 because he identifies himself as Alpha and Omega, the beginning and the end.³⁰ Christ identifies himself as Alpha and Omega in many other scriptures.³¹ These first and last letters of the Greek alphabet combine to form a title unique to Jesus Christ.³² They describe his endless and eternal nature.³³ This name-title symbolizes Christ's saving work in this generation,³⁴ beginning with his physical creation of all things,³⁵ and his spiritual re-creation of all things during the resurrection at the end.³⁶ After all things on all the worlds of Christ's creation have been resurrected,³⁷ then‒in the words of Paul‒all things shall be subdued unto him.³⁸ Christ will then deliver up the whole of his kingdom to the Father.³⁹

Christ promises eternal life to the obedient,⁴⁰ saying: I will give unto him that is athirst of the fountain of the water of life freely.⁴¹ Christ is the source of living water⁴² that comes from the fountain of the water of life.⁴³ Revelation 7:16-17 contains the same promise⁴⁴ to all people that thirst spiritually.⁴⁵ Spiritually thirsty people are those willing to endure great tribulation to drink the living water⁴⁶ that Christ will freely or abundantly give to them.⁴⁷ People that overcome tribulation and keep the commandments can abundantly drink the living waters of everlasting life⁴⁸ because they have washed their robes, and made them white in the blood of the Lamb.⁴⁹

Revelation 21:7: He that overcometh shall inherit all things; and I will be his God, and he shall be my son.

Overcoming tribulation is a common theme in the Book of Revelation.⁵⁰ Christ reaffirms here, as he did in Revelation chapters 2 and 3, that anyone who overcometh shall inherit all things.⁵¹ Inheritors of all things are exalted saints that will be given everything the Father has.⁵² They become heirs of God⁵³ and joint heirs with Jesus Christ.⁵⁴ This sharing of all things among all God's worthy children will occur even though Christ is God's only natural and lawful heir.⁵⁵ Christ is the only natural heir of the Father⁵⁶ because he was the first begotten in the spirit⁵⁷ and the only begotten in the flesh.⁵⁸ Christ is the only lawful heir of the Father because he was the only perfect person in premortality and mortality. He never forfeited his legal right to inherit because of sin or transgression.⁵⁹

God's other spirit children do not qualify to be God's natural or lawful heirs because they are not God's physical offspring and they disinherit themselves through sin and transgression.⁶⁰ No unclean thing can inherit the kingdom of God,⁶¹ which means they cannot enter or receive any part of the celestial kingdom.⁶² Nevertheless, people who are obedient to gospel law⁶³ can still overcome sin to qualify for exaltation⁶⁴ and joint heirship with Jesus Christ.⁶⁵ Joint heirs inherit and share all power, kingdoms, and glory of every other joint heir through the law of consecration,⁶⁶ which is a governing law among exalted Gods in all generations, and throughout all time and eternity.⁶⁷

Overcomers that qualify themselves as joint heirs of Jesus Christ will inherit all things from God as though they are a firstborn child of the Father.⁶⁸ Exalted saints can also rightfully claim their share in Christ's inheritance as the Firstborn because they are his metaphorical bride,⁶⁹ and also his spiritual sons and daughters.⁷⁰ Based on covenant relationships within the kingdom of God, the Savior divides his inheritance among his family of joint heirs.⁷¹ However, in accordance with the parable of the talents, Christ shares his kingdom in proportion to how people actually develop and use their talents in the day of their probation.⁷²

In Revelation 21:7, Christ further describes his relationship with each of his joint heirs, saying: I will be his God,⁷³ and he shall be my son.⁷⁴ These words express the doctrine of adoption⁷⁵ whereby people become the spiritual sons and daughters of Jesus Christ as they make and keep gospel covenants.⁷⁶ Christ is the spiritual father to all such people.⁷⁷ The words in Revelation 21:7 allude to Old Testament promises that Jehovah would be God to Israel and all her sons and daughters.⁷⁸ This universal promise extends to all the people that Christ physically creates and redeems on all his worlds.⁷⁹ By the power of the infinite atonement,⁸⁰ overcomers on all worlds stand as heirs in relation to Christ⁸¹ as Christ stands as an heir in relation to the Father.⁸² These adopted heirs become exalted members of the Church of the Firstborn,⁸³ and they jointly inherit all things, including worlds without end.⁸⁴
