The Conditions of the Millennium

Isa. 2:1 The word that Isaiah the son of Amoz saw concerning Judah and Jerusalem. 2 And it shall come to pass in the last days, that the mountain of the LORD'S house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it. 3 And many people shall go and say, Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem.
4 And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more. [5] O house of Jacob, come ye, and let us walk in the light of the LORD.
6 The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them. 7 And the cow and the bear shall feed; their young ones shall lie down together: and the lion shall eat straw like the ox. 8 And the sucking child shall play on the hole of the asp, and the weaned child shall put his hand on the cockatrice's den. 9 They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the LORD, as the waters cover the sea.

This refers to the Messianic Kingdom which is Israel's portion to be the center of all nations. War ceases in the 1000 years just like Revelation 20 says, "And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season" (v.3). The lion and the lamb will lay down together in peace.

Isa. 65.12 For thus saith the LORD, Behold, I will extend peace to her like a river, and the glory of the Gentiles like a flowing stream: 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.

In the millennium, those with bodies of flesh and blood will almost always live to be over 100 years of age. The peace of the nations will come.

Zech. 14.6 And it shall come to pass, that every one that is left of all the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the feast of tabernacles. 17 And it shall be, that whoso will not come up of all the families of the earth unto Jerusalem to worship the King, the LORD of hosts, even upon them shall be no rain.

This is the consequence of sin in the millennial kingdom, that any nation that does not go up to Jerusalem to worship God will receive environment hardships.

Isa. 30.26 Moreover the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days, in the day that the LORD bindeth up the breach of his people, and healeth the stroke of their wound.

Why does light increase? It is because scientifically speaking, we know the sun is going to get larger and larger until one day it burns up the earth.
