LIFE IN THE MILLENNIUM
The plagues through the tribulation and the great earthquake that caused the cities of the nations to fall, will cause such great devastation upon the earth that civilization as we know it will cease.
`And there were noises and thunderings and lightning; and there was a great earthquake, such a mighty and great earthquake as had not occurred since men were on the earth….and the cities of the nations fell…..every island fled away, and the mountains were not found..` (Rev. 16: 18 & 20)
No technology, no fuel, no food production, no medical facilities, no businesses of any kind, all will have crumbled, obliterated. There will be only few people upon the earth after the plagues, mass killings and persecutions.
Life in the millennium will have to start from the basics - agriculture and working together in family groups. There will be no more wars, so the weapons will be made into farm implements.
` They shall beat their swords into ploughshares, and their spears into pruning hooks; nations shall not lift up sword against nation, neither shall they learn war anymore.` (Micah 4: 3)
People will have to go up to Jerusalem to worship and celebrate the Feast of Tabernacles. If they don`t then God will not send any rain upon their land. This will cause famine, plagues, disease and death.
`And it shall be that whichever of the families of the earth do not come up to Jerusalem to worship the King, the Lord of hosts, on them there will be no rain.
If the family of Egypt will not come up and enter in, they shall have no rain; they shall receive the plague with which the lord strikes the nations who do not come up to keep the Feast of Tabernacles.` (Zech. 14: 17 & 18)
Jesus will not be sitting on a physical throne in Jerusalem for people to come and worship Him once a year. Jesus will not walking around the earth looking at those who are dying – children, elderly etc. Jesus will not be going around healing people as when He was on earth.
The people of the world are still sinful and need to turn to God. There are still consequences for man`s actions. God`s purpose is to show that even though Satan and his fallen angels have been removed, and God`s righteous rule is through Israel, that mankind will still rebel. Thus God is just to bring about a conclusion to time and bring in the judgments.
Because you have zero corroboration for your future millennium, you use "last days" passages relating to the here and now, and "new heavens, and a new earth" passages that relate to the eternal state, to apply to this imaginary invented age.
Christ appears with His holy angels (Matthew 13:41-43, 49 16:27 24:29-31 25:31-32, Mark 13:25-27, Luke 9:26, Revelation 14:14-20) and the New Jerusalem (John 14:1-3, Hebrews 11:8-10, 13-16, 13:14. Revelation 3:11-12, 21:1-4).
The wicked, to a man, are immediately destroyed at Christ’s return, as in Noah and Lot’s day (Joel 2:1-3, Joel 2:10-11, Isaiah 13:6-12, Malachi 4:1-3, Matthew 3:12, Luke 17:27-30, I Thessalonians 5:2-4, II Thessalonians 1:7-10, 2 Peter 2:5-9, Revelation 19:17-21 and Revelation 20:9).
There is a general resurrection/judgment (singular) of all mankind at the coming of Christ (Matthew 10:15, 12:36, 16:27, 25:31-46, John 5:21-30, 6:39-44, 54, 10:42, 11:21-27, 12:48, 17:30-32, 24:15, Acts 10:42, 17:30-31, Romans 2:4-8, 14:10-12, 1 Corinthians 3:6-8, 11-15, 1 Corinthians 4:5, 2 Corinthians 5:10, 2 Timothy 4:1-8, 2 Thessalonians 1:5-8, 1 Timothy 5:24, Hebrews 9:27, 10:27, 2 Peter 2:9, 3:7, 1 Peter 4:1-5, 1 John 4:17, and Revelation 19:11, 20:11-15, 22:12).
Satan cast into the Lake of Fire (Isaiah 26:19, II Thessalonians 2:1-9 Revelation 20:10). This occurs before the heaven and earth pass away in Revelation 20.
There is a climactic conflagration (Job 14:12-14, Isaiah 13:9-11, Isaiah 34:1-4, 8, Isaiah 65:17-21, Isaiah 66:22-24, Joel 2:3, Joel 2:10-11, Malachi 4:1-3, Matthew 24:29-30, Matthew 24:35-44, Mark 13:24-26, Luke 21:25-27, Romans 8:18-23, 1 Corinthians 15:23-24, 2 Thessalonians 1:7-10, 2 Peter 3:10-13, Hebrews 1:10-12, Revelation 6:13-17, Revelation 16:15-20, Revelation 19:11-16 and Revelation 20:11-15).
Perfection arrives with the age to come (Luke 20:27-36, Romans 8:19-23, 1 Corinthians 15:50-55, 2 Peter 3:3-13 Philippians 3:20-21, 1 Peter 4:3-7, Hebrews 1:10-12 and Revelation 20:11-15, 21:1-5).
The age to come possesses no mortals. The wicked are destroyed at His appearing (2 Samuel 22:9, Job 41:20-21, Psalm 18:7-8, 37:9-11, 50:1-6, 68:1-3, 97:3-5, Isaiah 11:4-5, 13:9, 30:33, 66:15-17, Joel 2:1-3, 2:10-11, Nahum 1:1, 5-6, Malachi 4:1, Luke 17:26-30, 20:34-36, Romans 8:19-23, 1 Corinthians 6:9, 13:8-13, 15:50-55, 1 Thessalonians 4:15-5:3, II Thessalonians 1:4-10, Revelation 16:15-21, 19:11-18, Revelation 21-22).
1 Corinthians 13:12, Ephesians 4:13 and Revelation 10:5-7 show that the curtain coming down on the mystery of God, thus confirming we are at the end of time and entering into eternity when all will finally be revealed.
This is a water-tight argument to me that the second coming is “the end.”
