During the reign of Jesus and the Saints in the Millennial Kingdom, the curse has not been fully lifted from the Cosmos. The land across the planet will produce food in a way that none on earth has experienced since Adam and Eve’s exit from paradise but Israel will enjoy the greatest level of production. It will be restored to be like the Garden of Eden but not the rest of the world. Men and women still marry and have children. They still die but have a longer life span.
The millennium is still a time of sin, death, rebellion, and harsh judgment. Its true character seems to fall between the present age (the “church age”) and the future sinless coexistence of the redeemed in the new heaven and new earth (Revelation 21). With reference to death in the millennial age, we read:
“No more shall there be in it an infant who lives but a few days, or an old man who does not fill out his days, for the young man shall die a hundred years old, and the sinner a hundred years old shall be accursed. Isaiah 65:20
“Thus says the Lord of hosts: old men and old women shall again sit in the streets of Jerusalem, each with staff in hand because of great age. And the streets of the city shall be full of boys and girls playing in its streets.” Zechariah 4:5
Also, it appears that the curse has been lifted off the animals in Israel but we are not told if that is the case in the rest of the world.
“The wolf shall dwell with the lamb, and the leopard shall lie down with the young goat, and the calf and the lion and the fattened calf together, and a little child shall lead them. The cow and the bear shall graze; their young shall lie down together, and the lion shall eat straw like the ox. The nursing child shall play over the hole of the cobra, and the weaned child shall put his hand on the adder’s den. They shall not hurt or destroy in all my holy mountain; for the earth shall be full of the knowledge of the Lord as the waters cover the sea.” Isaiah 11:6-9

“The wolf and the lamb shall graze together; the lion shall eat straw like the ox, and dust shall be the serpent’s food. They shall not hurt or destroy in all my holy mountain.” Isaiah 65:25
The river that emanates from the new Temple of God in Jerusalem gives us proof that the river brings life to a fallen world.
“Son of man, have you seen this?… when the water flows into the sea, the water will become fresh. And wherever the river goes, every living creature that swarms will live, and there will be very many fish... And on the banks, on both sides of the river, there will grow all kinds of trees for food. Their leaves will not wither, nor their fruit fails, but they will bear fresh fruit every month because the water for them flows from the sanctuary. Their fruit will be for food, and their leaves for healing.” Ezekiel 47:9-12
EVIDENCE OF MAN’S PAST REBELLION
“But its swamps and marshes will not be healed; they will be given over to salt.” Ezekiel 47:11
The remaining salted areas are emblematic of the transitional nature of the Millennium. The saltiness of the Dead Sea can rightly be understood to symbolize death. Even with Jesus reigning from David’s throne there will still be death, though it is diminished.
WASTELANDS
Edom in Southern Jordan: The most comprehensive description of Edom’s future is found in Isaiah 34:8-10.
“For the Lord has a day of vengeance, a year of recompense for the cause of Zion. And the streams of Edom shall be turned into pitch, and her soil into sulfur; her land shall become burning pitch. Night and day it shall not be quenched; its smoke shall go up forever. From generation to generation, it shall lie waste; none shall pass through it forever and ever.” Isaiah 34:8-10
In Jeremiah, it is compared to Sodom and Gomorrah. Its devastation is the result of God avenging Israel. “Because of the violence done to your brother Jacob, shame shall cover you, and you shall be cut off forever.” Obadiah 1:10
Life will not be prematurely cut off by pestilence and war, but man will live long: “for like the days of a tree shall the days of my people be, and my chosen shall long enjoy the work of their hands.” Isaiah 65:22b. The age of a hundred will be thought of as dying young; even the sinner, dying before his time as the penalty of his guilt, will live out 100 years. With this view, the effect of human sin will be reduced, but not eradicated. Death will still exist. Only on the New Earth will God finally wipe away all tears (Rev 21.4). Man’s sinful human nature will also result in national rebellion against Christ’s rule and will be firmly dealt with. Nations will serve the Lord or be punished severely. They will need to go up to Jerusalem and observe at least the Feast of Tabernacles or there will be no rain on their land.
“And if any of the families of the earth do not go up to Jerusalem to worship the King, the Lord of hosts, there will be no rain on them. And if the family of Egypt does not go up and present themselves, then on them there shall be no rain; there shall be the plague with which the Lord afflicts the nations that do not go up to keep the Feast of Booths. This shall be the punishment to Egypt and the punishment to all the nations that do not go up to keep the Feast of Booths.” Zechariah 14:17-19
Work will be a blessing, not a curse. Moreover, the wise use of technology will be expanded.
“They shall build houses and inhabit them; they shall plant vineyards and eat their fruit. They shall not build and another inhabit; they shall not plant and another eat; for like the days of a tree shall the days of my people be, and my chosen shall long enjoy the work of their hands. They shall not labour in vain or bear children for calamity, for they shall be the offspring of the blessed of the Lord, and their descendants with them.” Isaiah 65:21-23
“Foreigners shall build up your walls, and their kings shall minister to you; for in my wrath I struck you, but in my favour, I have had mercy on you. Your gates shall be open continually; day and night they shall not be shut, that people may bring to you the wealth of the nations, with their kings led in procession. For the nation and kingdom that will not serve, you shall perish; those nations shall be utterly laid waste.” Isaiah 60:10-12
