Revelation 22:1 "And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb. 2 In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations. 3 And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him: 4 And they shall see his face; and his name shall be in their foreheads. 5 And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever. 6 And he said unto me, These sayings are faithful and true: and the Lord God of the holy prophets sent his angel to shew unto his servants the things which must shortly be done."
22:1 - The water of life is a river in Eternity that flows from the throne of God, down alongside the street and the trees near the river will have their roots in it (Revelation 22:17, John 4:14).
22:2 - There are trees called the Tree of Life in Eternity that heals the saved Gentile nations (Ezekiel 47:12, Revelation 21:14, 24). They will come through twelve gates (Deut. 32:7-9). The Gentile nations will be separated into twelve nations like the Jewish nations and there are twelve months in a year (Job 14:1-5, Acts 17:24-27). The twelve nations are probably 1. North America 2. Central America 3. South America 4. Antarctic Continent 5. Arctic Circle 6. Asia 7. Africa 8. Australia 9. West Indies 10. East Indies 11. Greenland 12. Europe. When these people take the Tree of Life, they receive eternal life and most likely their offspring will also. These people partaking of the Tree of Life are the Tribulation and Millennium saints. The Church Age saints already have eternal life and glorified bodies, so they do not need to partake of it. These Tribulation and Millennium saints have male and female bodies, so they will populate outer space. The Church Age saints have a body like Christ, so they do not marry in Eternity.
22:3-5 - This reign starts in the Millennium and goes into Eternity (Daniel 17:14,18). The "they" in verse 5 probably refers to the Church Age saints in the city and the Tribulation saints because of the mark on their forehead (Revelation 14:1). There is no sun or moon in the city of New Jerusalem, but the sun and moon is still there for the new earth (Psalms 89:29-37). In verse 3, you see that the Adamic curse is removed in Eternity. Also, in verse 3 it says that we will serve Jesus. Serving might include transporting and communicating with the Tribulation and Millennium saints in out space.
22:6 - Shortly be done refers to someone in the Tribulation.
Revelation 22:7 "Behold, I come quickly: blessed is he that keepeth the sayings of the prophecy of this book. 8 And I John saw these things, and heard them. And when I had heard and seen, I fell down to worship before the feet of the angel which shewed me these things. 9 Then saith he unto me, See thou do it not: for I am thy fellowservant, and of thy brethren the prophets, and of them which keep the sayings of this book: worship God. 10 And he saith unto me, Seal not the sayings of the prophecy of this book: for the time is at hand. 11 He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still. 12 And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be. 13 I am Alpha and Omega, the beginning and the end, the first and the last. 14 Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city. 15 For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie."
Final exhortations about the book of Revelation
22:7 - The book is the book of Revelation. It can be practically applied to the Bible.
22:8-9 - The angel might be Daniel(Daniel 12:4-13) because in the resurrection the saints are as angels (Matthew 22:30). Remember where Daniel messed up and allowed the king to bow before him. This angel is careful not to let that happen again, so it could be Daniel. Obey the last two words of verse 9, "worship God". Cross reference for verse 8: Revelation 21:9
22:10 - The book is book of Revelation. "The time is at hand" refers to the Lord's coming (Revelation 22:7,12,20). Cross reference: Mark 1:10
22:11 - "Still" here means "the same condition". Whatever condition a person is in when the Lord comes, that will be his condition forever. The time to turn to Jesus is before He comes back.
22:12 - This could be applied to a Tribulation saint waiting on the Second Advent or a Church Age saint waiting on the Judgment Seat of Christ. Cross references: Isaiah 40:10, 62:11
22:13 - Cross reference: Isaiah 44:6
22:14 - Cross references: Revelation 21:24 and Hebrews 1:14
22:15 - Dogs is a reference to actual people (2 Peter 2:22).
Revelation 22:16 "I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star. 17 And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely. 18 For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: 19 And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book. 20 He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus. 21 The grace of our Lord Jesus Christ be with you all. Amen."
A final invitation, warning, prayer and promise
22:16 - Jesus is the Morning Star, not Satan like the new versions say. The Morning star is the sun that comes up in the morning (Malachi 4:2). Cross reference: Revelation 1:4,11
22:17 - This could be applied to a person in the Church Age because it is a faith alone invitation. The word "freely" here was revised in Genesis 3:2 by Eve (Genesis 2:16).
22:18 - This is a reference to the book of Revelation, but could be practically applied to the Bible (Deut. 4:2, Proverbs 30:6). Notice God warns about taking away from His words in three places, at the beginning, middle and end of the Bible. Any other book that claims to be the word of God goes against these three verses, including the new versions and other religious books.
22:19 - No one should change one word of the King James Bible or book of Revelation, even though we have Eternal Salvation today.
22:20 - "Amen" means "that's so".
22:21 - A cross reference to the grace of our Lord Jesus Christ is found in 2 Cor. 8:9. This is a reminded that salvation is by the grace of Jesus Christ.
