Look at these wonderful words,
‘He [Jesus] will judge between the nations and will settle disputes for many peoples.’ Isaiah 2:4a
That refers to the Millennium when Jesus will reign from Jerusalem for a thousand years (referenced in Revelation 20:4-6). It will be a wonderful time on this present earth. Jesus will settle the disputes of Russia, China, North Korea, Iran, Ukraine, the United States and many other nations. Not only that,
‘They will beat their swords into plough shares and their spears into pruning hooks. Nation will not take up sword against nation, nor will they train for war any more.’ Isaiah 2:4b
Just think! There will be no more armaments factories. It will not matter who has what grudge or which nation wants to expand its territory or settle arguments, there will be no more war.
The Millennium is a prelude (forerunner) of the coming eternal Kingdom of God. What a future for God’s children!
