Speaking of the 1,000 years...
Isaiah 65:20
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.
How do YOU define this verse? What do you believe Isaiah means? Bear in mind the context for understanding this verse shall be fulfilled when "I create a new heavens and a new earth". The new heavens and new earth are being created as the gospel of the Kingdom of God through Christ is proclaimed unto all the earth. It is now, in this age of time the Kingdom of God in heaven, a spiritual not physical Kingdom. God is creating something altogether new, not as things physically exist.
Isa 65:17 ¶ For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
Isa 65:18 But be ye glad and rejoice for ever in that which I create: for, behold, I create Jerusalem a rejoicing, and her people a joy.
Isa 65:19 And I will rejoice in Jerusalem, and joy in my people: and the voice of weeping shall be no more heard in her, nor the voice of crying.
Isa 65:20 There shall be no more thence an infant of days, nor an old man that hath not filled his days: for the child shall die an hundred years old; but the sinner being an hundred years old shall be accursed.
Isa 65:21 And they shall build houses, and inhabit them; and they shall plant vineyards, and eat the fruit of them.
Isa 65:22 They shall not build, and another inhabit; they shall not plant, and another eat: for as the days of a tree are the days of my people, and mine elect shall long enjoy the work of their hands.
Isa 65:23 They shall not labour in vain, nor bring forth for trouble; for they are the seed of the blessed of the LORD, and their offspring with them.
Isa 65:24 And it shall come to pass, that before they call, I will answer; and while they are yet speaking, I will hear.
Isa 65:25 The wolf and the lamb shall feed together, and the lion shall eat straw like the bullock: and dust shall be the serpent's meat. They shall not hurt nor destroy in all my holy mountain, saith the LORD.
