Joel 2 - Introduction
A Prophecy For Pentecost
-- Joel Two --
Joel two sounds almost like a restatement of Joel one with the Pentecost prophecies added. Joel said that the people must assemble and that an announcement should be made that the day of the Lord is at hand. He described that day as a dark day of destruction. The people were urged to turn to God and to cry in repentance unto the Lord. The day of the Lord would be a day of darkness like nothing ever seen before.
God would send the army of locusts and a human army also against the nation of Judah. It would be an army of Judgment. This army would be terrible, powerful and very destructive. The nation would be left in terror. The army would be skilled in warfare and much disciplined. They would overpower the land of Judah. This would be the Lord's army and no one could stand before them. (Joel 2:11)
Joel called upon the people to return to the Lord in true repentance. He understood that God is "gracious and merciful, slow to anger, and a God of great kindness." If the people would, in repentance, fast and pray, perhaps God would change His mind about the punishment He would send blessings and Judah would not be reproached before other nations. The Lord would respond to their repentance by showing pity for the land and for the people.
Joel also proclaimed the future day of the Lord. Then God's Spirit would be poured out on all flesh and Judah and all others could return to a covenant relationship with God through Jesus Christ. Forgiveness of sins and spiritual blessings would then be available to all that call upon the Lord in obedience.
