Joel 2:30

The Prophet seems here to contradict himself; for he had hitherto promised that God would deal kindly and bountifully with his people; and every thing he has said tended to elevate the spirits of the people and fill them with joy: but now he seems again to threaten them with God’s wrath and to strike miserable men with fear; who had not as yet a breathing time; for at the time the Prophet spoke, the Jews, we know, were in the greatest sorrow. What then is his purpose in adding a new cause of grief, as though they had not sorrow and lamentation enough? But it is rather an admonition than a threatening. The Prophet warns them of what would be, lest the faithful should promise themselves some happy condition in this world, and an exemption from all cares and troubles; for we know how prone men are to self-indulgence. When God promises any thing, they flatter themselves and harbor vain thoughts, as though they were beyond the reach of harm, and free from every grief and every evil. Such indulgence the flesh contrives for itself. Hence the Prophet reminds us, that though God would bountifully feed his Church, supply his people with food, and testify by external tokens his paternal love, and though also he would pour out his Spirit, (a token far more remarkable,) yet the faithful would continue to be distressed with many troubles; for God designs not to deal too delicately with his Church on earth; but when he gives tokens of his kindness he at the same time mingles some exercises for patience, lest the faithful should become self-indulgent or sleep on earthly blessings, but that they may ever seek higher things.

We now then understand the Prophet’s design: he intends not to threaten the faithful, but rather to warn them, lest they should deceive themselves with empty dreams, or expect what is never to be, that is, to enjoy a happy rest in this world. Besides, the Prophet regards also another thing: we know indeed that men are hardly led to seek the grace of God, except when they are, as it were, forcibly drawn; hence spiritual life is neglected, and whatever belongs to the celestial kingdom, when we have all kinds of supplies on earth. The Prophet then commends here the spiritual grace of which he speaks, for this reason, — that the condition of men would be miserable, were not the Lord to exhilarate their minds and refresh them with the comfort which we have already noticed. — How so? There will be prodigies in heaven and on earth, the sun shall be turned into darkness, and the moon into blood, and all things shall be in disorder and in horrible darkness. What then would become of men, were not God to shine on them by the grace of his Spirit, to support them under such a confusion in heaven and on earth, and to show himself to be their Father?

We then see that this was added for the fuller commendation of God’s grace, that men might know, that they would be much more miserable if God called them not to himself by the shining light of his Spirit. And that this was the Prophet’s design, we may learn from the discourse of Christ, which he made to his disciples a short time before his death. They asked what would be the sign of his coming, when he reminded them of the destruction of the temple, (Matthew 24:3). They thought that he would immediately accomplish that triumph of which they had heard, that they would be made participators of that eternal beatitude of which Christ had so often spoken to them. Christ then warned them not to be deluded with so gross a notion. He spoke of the destruction of Jerusalem, and then declared that all these things would be only the presages of evils — “These,” he says, “shall be only the preludes; for tumults will arise, wars shall be, and all places will be full of calamities; in a word, there will be an immense mass of all evils.” As Christ then corrected the mistake, with which the minds of the disciples were imbued, so the Prophet here checks vain imaginations, lest the faithful should think that Christ’s kingdom would be earthly, and fix their minds on corn and wine, on pleasures and quietness, on the conveniences of the present life: I will give you, he says, prodigies in heaven and on earth blood, fire, and dark clouds; the sun all be turned into darkness, and the moon into blood, before it shall come —the day of Jehovah, great and terrible
