I've been working on this since this morning as I could never figure out where the part came in where Jesus steps foot on the mount of Olives in His second coming. I present this for your consideration and not to be debated, only discussed.
We do not enter the Millennial Kingdom here on earth in our natural bodies, but in new glorified bodies, 1 Corinthians 15:51-54. When Christ returns in the air we are then caught up to meet Him in the air and so shall we ever be with the Lord as He has made us unto our God kings and priests and we shall reign on the earth as we rule with Him over the nations as His enemies have become His footstool, 1 Thessalonians 4:16-18; Rev 5:10; Psalms 110:1-4; Hebrews 10:12, 13.
Matthew 24:29-31 Jesus descends down from heaven with His army of the host of heaven as He sends His angels out to the four corners of the earth to gather His own to Him. He will destroy the beast and false prophet casting them into the lake of fire, Rev 19:15, 16. The remnant in Rev 19:21 are the kings (Rulers of every nation) on the earth and their armies that followed after the beast and his false prophet that go out to the battle of Armageddon as this army is sent out to kill Christ when they see Him and the saints with Him return and plants His feet on the mount of Olives, Zechariah 14:1-4.
The remnant, like the beast and false prophet, will be slain by the very words Jesus speaks of their demise and at that time Satan will be chained and bound so he can not interfere with those ungodly that are still alive on earth that become the footstool of Christ. Then the kingdoms of this world are become the kingdoms of our Lord and of his Christ and He shall reign for ever and ever and the saints will then begin to rule over the nations here on earth, Rev 11:15; 5:10; 20:1-3; Matthew 5:5.
Rev 20:7-10 Those that have rejected Christ that still remain on earth after the beast, false prophet and all the kings/rulers from every nation are destroyed are those who are the numbering as the sand of the sea. These are the enemy of God that Satan uses to battle against the saints that are camped upon the breadth of the earth. Psalms 2:7-10; 110; Ezekiel 36; 37; Rev 20:7-9 the saints are camped not only in Jerusalem the beloved city of God, but also throughout the breadth of the earth. It's only the 144,000 generational Jews that believe in Christ that have returned to Jerusalem. After the 1000 years are fulfilled Satan is set loosed for a season and goes out to deceive the nations as he gathers the enemies of Christ to battle against the saints as the numbering of unbelievers is like the sand of the sea. As the enemy surrounds the camp of the saints God sends fire down from heaven and destroys the enemy and Satan is cast onto the lake of fire.
John 5:28, 29; Rev 20:11-15, now comes the Great White throne judgment as the books are opened with one of them being the Lamb's book of life where all the saints of God have their names written as they have part of the first resurrection of eternal life on such the second death hath no power, Rev 20:6; 1 Corinthians 15:54-57. The other book is opened being the book of damnation where the enemies of God that were killed while trying to destroy the camp of the saints are now condemned and cast into the lake of fire. And death and hell were cast into the lake of fire. This is the second death. And whosoever was not found written in the book of life was cast into the lake of fire. While the saints on on the earth it will be made new again and the New Jerusalem is ushered down from heaven.
Side note: IMO 1000 years in Rev 20 is not literal years, but only symbolic of a certain period of time as nowhere else in scripture other than Rev 20 does it mention a literal 1000 year reign of Christ here on earth, but symbolic as in Deuteronomy 7:9; 1Chronicles 16:15; Psalms 50:10; 90:4; 105:8 Ecc 6:6; 7:28; Daniel 5:1; 2Peter 3:8.
2 Peter is literal and refers to the Second Coming and the time of the reign with Christ.
It is the Sabbath rest.
The 7000th year.
Each 1000 years refers to a day of the week, prophetically.
We are approaching the end of the 6th prophetic day.
