The standard reply is that Christ reigns until He has conquered the last enemy which is death. This occurs at the Second Coming.
NO, in the 1000 Year earthly Kingdom, it says there will still be people dieing, even though they live hundreds of years. In fact it says they will be considered a Youth if they die at a Hundred years of age. We will be in our glorified immortal bodies, but the 144,000 will be in their mortal bodies, repopulating Israel, and they will still grow old and die. THEREFORE, Judgement Day, after that 1000 years, just before the Eternal State, is when DEATH is cast into the Lake of Fire:
Revelation 20:14-15 (CSBBible)
[SUP]
14 [/SUP] Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire.
[SUP]
15 [/SUP] And anyone whose name was not found written in the book of life was thrown into the lake of fire.
That is Judgement Day. ☝
1 Corinthians 15:53 (CSBBible)
[SUP]
53 [/SUP] For this corruptible body must be clothed with incorruptibility, and this mortal body must be clothed with immortality.
That happened at the Rapture to us before the Tribulation even starts. ☝
Isaiah 65:18-25 (HCSB)
[SUP]
18 [/SUP] Then be glad and rejoice forever in what I am creating; for I will create Jerusalem to be a joy and its people to be a delight.
[SUP]
19 [/SUP] I will rejoice in Jerusalem and be glad in My people. The sound of weeping and crying will no longer be heard in her.
[SUP]
20 [/SUP] In her, a nursing infant will no longer live only a few days, or an old man not live out his days. Indeed,
the youth will die at a hundred years, and the one who misses a hundred years will be cursed.
[SUP]
21 [/SUP] People will build houses and live ⌊in them⌋; they will plant vineyards and eat their fruit.
[SUP]
22 [/SUP] They will not build and others live ⌊in them⌋; they will not plant and others eat. For My people’s lives will be like the lifetime of a tree. My chosen ones will fully enjoy the work of their hands.
[SUP]
23 [/SUP] They will not labor without success or bear children ⌊destined⌋ for disaster, for they will be a people blessed by the LORD along with their descendants.
[SUP]
24 [/SUP] Even before they call, I will answer; while they are still speaking, I will hear.
[SUP]
25 [/SUP] The wolf and the lamb will feed together, and the lion will eat straw like the ox, but the serpent’s food will be dust! They will not do what is evil or destroy on My entire holy mountain,” says the LORD.
This is talking about the 144,000 and their descendants. ☝
