Joel 1:14, 2:12-13 “Consecrate a fast; call a solemn assembly. Gather the elders and inhabitants of the land to the house of the Lord, your God, and cry out to the Lord. ‘Yet even now’ declares the Lord, ‘return to me with all your heart, with fasting, with weeping, and with mourning; and rend your hearts and not your garments.’ Return to the Lord your God, for he is gracious and merciful, slow to anger, and abounding in steadfast love; and he relents over disaster.”
Summary of the Book of Joel
"Practical Application: Without repentance, judgment will be harsh, thorough, and certain. Our trust should not be in our possessions but in the Lord our God. God at times may use nature, sorrow, or other common occurrences to draw us closer to Him. But in His mercy and grace, He has provided the definitive plan for our salvation—Jesus Christ, crucified for our sins and exchanging our sin for His perfect righteousness (2 Corinthians 5:21). There is no time to lose. God’s judgment will come swiftly, as a thief in the night (1 Thessalonians 5:2), and we must be ready. Today is the day of salvation (2 Corinthians 6:2). “Seek the LORD while he may be found; call on him while he is near. Let the wicked forsake his way and the evil man his thoughts. Let him turn to the LORD, and he will have mercy on him, and to our God, for he will freely pardon” (Isaiah 55:6-7). Only by appropriating God’s salvation can we escape His wrath on the Day of the Lord."
