Micah 4:1-3 and Isaiah 2:2-4
In the last days, the Temple of the Lord in Jerusalem will become the most important place on earth. People from all over the world will go there to worship. Many nations will come and say, "Come, let us go up to the mountain of the Lord, to the Temple of the God of Israel. There he will teach us his ways, so that we may obey him." For in those days the Lord's teaching and his word will go out from Jerusalem.
The Lord will settle international disputes. All the nations will beat their swords into plowshares and their spears into pruning hooks. All wars will stop, and military training will come to an end.

I hope this happens soon. Who knows maybe every nation on earth will recall all their guns to be made into combines! Wouldn't it be sweet if God Himself would arbitrate between the countries in the middle east? And between us and the middle east? I don't know if either side would win the dispute, but hey, God will do what is just!
