In our study of Joel chapter three, we will look at what the Bible says about the end of the nations and the coming new world government.
"'In those days and at that time, when I restore the fortunes of Judah and Jerusalem, I will gather all nations and bring them down to the Valley of Jehoshaphat. There I will enter into judgment against them concerning my inheritance, my people Israel, for they scattered my people among the nations and divided up my land. They cast lots for my people and traded boys for prostitutes; they sold girls for wine that they might drink.'" NIV translation
The phrase "at that time" refers us back to the Millennial Reign as we saw in chapter two. At the end of this time of peace, we see that ALL nations will be drawn to this valley for judgment.
The Valley of Jehoshaphat refers to part of the Kidron Valley that is between the Temple Mount and the Mount of Olives.
We see that the nations that come to attack Jerusalem will be judged based on how they have treated God's people (the Jews). We see these same events described by John in Revelation 20.
It is important to note, here, that ALL the nations of the earth will come to this valley. There are those who say that the USA will never abandon the state of Israel but God's word says they will. How is this possible? The answer is quite simple in that all of these events will take place after the church has been taken out of the world. Christians are the greatest friends of the Jews and, when we are removed, the USA will turn against Israel.
"'Now what have you against me, O Tyre and Sidon and all you regions of Philistia? Are you repaying me for something I have done? If you are paying me back, I will swiftly and speedily return on your own heads what you have done. For you took my silver and my gold and carried off my finest treasures to your temples. You sold the people of Judah and Jerusalem to the Greeks, that you might send them far from their homeland.'" NIV translation
Now, we see that God speaks to the nations of Joel's time with the charges against them. This also speaks of the attitude that will bring the nations against Jerusalem for the final judgment. The Millennial Reign is a time of example in showing the world what it is like when God is reigning in power. Instead of repentance and accepting God's authority, this time will bring about jealousy on the part of the nations which will draw them to this valley for judgment.
