Isaiah 2:4. “And He shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war any more.
Jehovah, the Mighty One of Israel, will be the ‘united nations’ of the Millenial Kingdom. The Righteous Judge will administer justice in international affairs, and there will be no more war.
Notice that He will rebuke many people. The Kingdom is NOT heaven; that comes after the Kingdom. There will still be, in many hearts, a spirit of rebellion that God will see, and will rebuke. Because He is Jehovah, people will be able to put down their swords and spears.
There won’t be any more elections! No longer will deceitful, power-hungry politicians control the people. God, Who knows the hearts of mankind, will be the Authority Whom no one will fool.
We will not learn how to make war any more.
