In Joel Chapter 2, the inner story is this:

Because sensual people had destroyed the "whole church" with falsities and evil, it was time for the Lord to come and execute His judgment. The variety of insanities of the sensual people caused good and truth, and knowledges, to be dispersed.

The Lord was going to wage war against the sensual people. He blew the trumpet to sound the alarm. His approach would cause those who were opposed to Him to tremble. Upon the proud and resistant, there was to be a terrible judgment. The evil felt the approach of the Lord, and they did not want to lose their power.

So the evil took on the appearance of "steed horses." They hooked themselves up to chariots. They started fires in the stubble of the field. A call was made to form up a mighty army. They lined up in a formation and did not break rank. They lunged with their weapons, running throughout the city. They climbed the walls of the city, breaking through the windows of the houses like thieves.

The battle was not without some temporary negative aspects. The action of the sensual person caused the darkening of the sun and moon, and it made the stars of heaven fall from the sky.

Another call was made by the Lord to His people. He asked them to return to Him with "all your heart, with fasting, with weeping and mourning…Rend your hearts and not your garments." The exhortation here is to be converted and repent, and to be wise.

We are taught that the Lord will establish the church again; He will give it goods and truths, and He will remove evil and thus hell. The new church will have trust in the Lord and will acknowledge Him from the heart. The Divine of the Lord will fill those of the new church with all things, and He will vivify them. Falsities of evil and evils of falsity will dissipate in the "day of His judgment." Those who acknowledge the Lord will be saved.

The theme of this chapter is a call to "awake," to hear the Word of the Lord and respond to His battle cry. For there is no doubt regarding the outcome of this battle: The Lord will, in the end, win the battle for His Word and His Church.
