Rev 22:12 "And behold, I am coming quickly, and My reward is with Me, to give to every one according to his work. I am the Alpha and the Omega, the Beginning and the End, the First and the Last. Blessed are those who do His commandments, that they may have the right to the tree of life, and may enter through the gates into the city."
Rev 21:1 Now I saw a new heaven and a new earth, for the first heaven and the first earth had passed away. Also there was no more sea.
The present universe is only temporal which the scientists can testify to you. Our Father wants to give us the eternal bliss and rest with Him in the New Earth without the presence of the annoying, evil, wicked, and abominable Satan.
At Rapture, the saints will all be transformed into their new glorious incorruptible bodies and they will follow our Lord back to heaven. Immediately after Rapture the opening of the 7th Seal will bring the Wrath of God upon all men, (except for the 144,000 sealed Israelites). For 42 months they will suffer excruciating pains and even if they wish to die they cannot die. At the end of the wrath will be the Battle of Armageddon, where Jerusalem will be on verge of being conquer by the enemies. At that very moment put Lord Jesus will stand on Mount Olive splitting it into two for the Israelites to escape. With His brightness He will kill all those surrounding Jerusalem that their eyes will melt inside their sockets.
Jesus Millennium Rule
After the people have cleared and buried the dead bodies from ground, our Lord Jesus will come down with His resurrected saints to establish His Millennium Rule (after having tied up the Devil and cast him into the sealed bottomless pit). The whole world will bring sacrifices to worship our Lord on His Holy mountain in Jerusalem.
Rev 20:7-8 Now when the thousand years have expired, Satan will be released from his prison and will go out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to battle, whose number is as the sand of the sea.
After the thousands years, the Devil will be set free and once again he will lead the people to rebel against our Lord at the final battle. The Devil will be defeated and cast into the eternal Lake of fire with the beast and false prophets.
New Heaven and New Earth
Rev 21:2-3 Then I, John, saw the holy city, New Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from heaven saying, "Behold, the tabernacle of God is with men, and He will dwell with them, and they shall be His people. God Himself will be with them and be their God."
After the creation of the New Heaven and the New Earth, our Lord Jesus and His resurrected saints will be on the New Earth. Coming down from the New heaven will be the New Jerusalem housing the tabernacle of God with God the Father, the Holy Spirit and the bride of the Lamb dwelling within. Our Lord Jesus will then enter the New Jerusalem to claim His bride and they will be with God the Father forever.
Brethren, let's have complete faith in Him and His promises so that we can keep His words and be overcomers: " He who overcomes shall inherit all things, and I will be his God and he shall be My son. But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death.". (Rev 21:7-8)
