Although the immediate promise would be to the restoration of Israel from the scattering of the Assyrian and Babylonian captivities, everything in this chapter is to occur ‘after the outpouring of God’s Spirit upon all flesh’. God will judge all nations on account of His people, especially Judah’s enemies, Tyre, Sidon, Philistia, Egypt and Edom.
Gathering the nations is a reference to the gathering of spiritual Israel out of all nations through the preaching of the Gospel, Matthew 28:19-20 / Mark 16:15-16 / Acts 8:4.
The Valley of Jehoshaphat isn’t a literal place in Palestine but a figurative place where God will bring His judgment, kind of like the place ‘Armageddon’ in Revelation 16.
The Valley of Jehoshaphat which means ‘God shall judge’ and ‘Armageddon’ are the places where God will vent His anger and wrath upon all those who oppose Him. Although God would oppose His people’s enemies and bring them out of all nations to which they had been taken captive, Ezra / Nehemiah.
The fulfilment of this prophecy is seen in the Gospel where God calls out people from the captivity of their sin, 2 Thessalonians 2:14. When the Israelites were taken into Assyrian and Babylonian captivity, their captors showed little consideration for the people.
‘They cast lots for my people’, refers to the sinfulness of Israel’s enemies, drunkenness, and human slavery, especially child abuse, are prominent here.
Tyre, Sidon and Philistia had mistreated God’s people and they will reap what they sow. They will be treated as they treated others around them, especially God’s people. They stole the temple treasures of Israel and placed them in their pagan temples of false gods. They traded in slavery by selling Israelites to other nations.
Later, the very people to whom they had sold God’s people, the Greeks, would eventually be the people who would conquer and sell them as slaves to other nations. They eventually reaped what they sowed when Alexander the Great conquered their cities.
The nations, Tyre, Sidon, Philistia, Egypt and Edom are called to prepare for battle, they are called to come to the ‘Valley of Jehoshaphat’, where the Lord will judge the nations. This again, speaks of judgement on Judah’s enemies. God will overthrow these people and He will use the judgment of these people in reference to any people who come up against Judah.
The word, ‘warriors’ means mighty ones, this could be either angel, Daniel 9:10ff or cherubim, Ezekiel 10. Whoever they are, they are God’s chosen fighters. God’s enemies will have no chance.
Notice that Joel calls the place the ‘valley of decision’ which simply means the valley of judgment. In other words, the nations were called by God to judgment.
The nations were so evil, that God now decides to judge them and destroy them, which meant God’s people would be free from them. This is a picture of God’s kingdom standing and the earthly kingdoms falling.
As we noted earlier, the mention of the sun and the moon being darkened is figurative judgment talk, which symbolises the end of the kings and rulers of the nations, Hebrews 12:22-29. In other words, there are going to be big changes.
God is described as roaring like a lion towards His enemies, Joel 2:11 / Jeremiah 25:30 / Amos 1:2. But at the same time, He speaks of hope and strength to His own people.
When God carried out His judgment on the nations, the promise was that no conquering strangers would pass through Jerusalem again and so, in the context of the text, we can see that Joel is speaking of the new Jerusalem, and spiritual city of God, the church, that descended from heaven, Revelation 21. In other words, no stranger, unbeliever, would pass through the church.
‘In that day,’ the blessings will be abundant, there will be blessings of security and there will be a future for God’s people. Judah shall be blessed by a ‘fountain, from the house of the Lord,’ God’s people are going to live in safety under the cleansing blood of the Messiah.
Egypt and Edom who symbolise God’s enemies will be desolate because of their violence. Judah and Jerusalem shall abide forever, acquitted of their guilt. God won’t free the wicked but bring just judgment on them for the harm that they brought on His people.
When difficult times come into our lives, they can actually be a blessing, if they turn us back to God, Amos 4:6-12 / Job 1:20-22. God sees all, the good and the bad, He sees those who oppose Him and His people and promises they will be judged.
He also promises that repentance is available to all, but if people don’t repent then they will be judged, 2 Corinthians 7:8-10 / Joel 2:13. Israel was chosen in 586 B.C. but in A.D.70 they were punished because they didn’t change their ways.
We must remember that ‘The Day of the Lord’ is coming for us all, 2 Peter 3:7-10, after which there will be no more chances to repent, and so we must prepare now, 2 Peter 3:11-14.
The good news is that God doesn’t want anyone to perish because He loves us too much and the reason He hasn’t returned yet is because He’s giving people time to come to Him.
"I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world."
