12 But there's also this, it's not too late - God's personal Message! - "Come back to me and really mean it! Come fasting and weeping, sorry for your sins!" 13 Change your life, not just your clothes. Come back to God, your God. And here's why: God is kind and merciful. He takes a deep breath, puts up with a lot, This most patient God, extravagant in love, always ready to cancel catastrophe. 14 Who knows? Maybe he'll do it now, maybe he'll turn around and show pity. Maybe, when all's said and done, there'll be blessings full and robust for your God! 15 Blow the ram's horn trumpet in Zion! Declare a day of repentance, a holy fast day. Call a public meeting. 16 Get everyone there. Consecrate the congregation. Make sure the elders come, but bring in the children, too, even the nursing babies, Even men and women on their honeymoon - interrupt them and get them there. 17 Between Sanctuary entrance and altar, let the priests, God's servants, weep tears of repentance. Let them intercede: "Have mercy, God, on your people! Don't abandon your heritage to contempt. Don't let the pagans take over and rule them and sneer, 'And so where is this God of theirs?'"
Matthew Henry's Commentary on Joel 2:12-17
Commentary on Joel 2:1-14
(Read Joel 2:1-14)
The priests were to alarm the people with the near approach of the Divine judgments. It is the work of ministers to warn of the fatal consequences of sin, and to reveal the wrath from heaven against the ungodliness and unrighteousness of men. The striking description which follows, shows what would attend the devastations of locusts, but may also describe the effects from the ravaging of the land by the Chaldeans. If the alarm of temporal judgments is given to offending nations, how much more should sinners be warned to seek deliverance from the wrath to come! Our business therefore on earth must especially be, to secure an interest in our Lord Jesus Christ; and we should seek to be weaned from objects which will soon be torn from all who now make idols of them. There must be outward expressions of sorrow and shame, fasting, weeping, and mourning; tears for trouble must be turned into tears for the sin that caused it. But rending the garments would be vain, except their hearts were rent by abasement and self-abhorrence; by sorrow for their sins, and separation from them. There is no question but that if we truly repent of our sins, God will forgive them; but whether he will remove affliction is not promised, yet the probability of it should encourage us to repent.
Commentary on Joel 2:15-27
(Read Joel 2:15-27)
The priests and rulers are to appoint a solemn fast. The sinner's supplication is, Spare us, good Lord. God is ready to succour his people; and he waits to be gracious. They prayed that God would spare them, and he answered them. His promises are real answers to the prayers of faith; with him saying and doing are not two things. Some understand these promises figuratively, as pointing to gospel grace, and as fulfilled in the abundant comforts treasured up for believers in the covenant of grace.
