Jeremiah 14:12

We pray to God daily, it may be said, and yet we do not fast daily. It is indeed true that prayer is more intent when we fast; but yet God requires not daily fastings, while he enjoins prayer both in the morning and in the evening, yea, he would have us to implore his grace continually. (1 Thessalonians 5:17) But when fasting is joined to prayer, then prayer becomes more earnest; as it is usually the case when there is any danger, or when there appears any evidence of God’s wrath, or when we labor under any heavy affliction; for we then not only pray but we also fast that we may be more free and more at liberty to pray. Besides, fasting is also an evidence that we are deprecating the wrath of God, while we confess that we are guilty before him; and thus also they who pray stimulate themselves the more to sorrow and to other penitential feelings. It is therefore the same as though he had said, “Even if they pray in no common manner and every day, and add fasting, so that greater fervor may appear in their prayers and extraordinary attention, yet I will not hear their cries, even because their heart is false.”

We further gather from this passage that fasting is not in itself a religious duty or exercise, but that it refers to another end. Except then they who fast have a regard to what is thereby intended — that there may be a greater alacrity in Prayer — that it may be an evidence of humility in confessing their sins — and that they may also strive to subdue all their lusts — except these things be regarded, fasting becomes a frivolous exercise, nay, a profanation of God’s worship, it being only superstitious. We hence see that fastings are not only without benefit except when prayers are added, and those objects which I have stated are regarded, but that they provoke the wrath of God as all superstitions do, for his worship is polluted.

But under the Papacy the reason given for fastings is, that they merit the favor of God. The Papists seek to pacify him by fasting as by a sort of satisfaction; they will have fasting to be a work of merit. I will not now speak of the numberless trifles which also pollute their fasting; but let us suppose that they are not superstitious in their choice of meats, in their hours, and in other childish follies, which are mere trumperies, nay, mockeries also to God — let us suppose them to be free from all these vices, yet the intention, as they call it, is nothing else but a diabolical error, for they determine that fasting is a work of merit and of satisfaction, and a kind of expiation. Let us then know, that though Jeremiah speaks of hypocrites, yet he briefly points out the design of fasting by mentioning prayer. So also Christ, when recommending fasting, makes mention of prayer. (Matthew 17:21; Mark 9:29) The same is done by Paul. (1 Corinthians 7:5.) But it ought to be noticed here, that though hypocrites joined before men prayer with fasting, they were yet rejected, for there was no sincerity in their hearts, but only an outward profession, a mere disguise. But God, as we have, seen, regards the heart, and sincerity alone pleases him.

The same thing is said of sacrificing, When they present sacrifices, or burnt — offerings, and an oblation, מנחה, meneche, that is, the daily offerings, I will not hear them, or, as he says in the second clause, I will not be pleased with them Sacrifice without prayers were no doubt vain and worthless, for as pr ayers were not acceptable to God without a sacrifice, so when sacrifice was without prayers it was only a vain shew these two things are then united as by an indissoluble knot, to offer sacrifices and to pray. Prayers, as I have said, cannot be acceptable to God without a sacrifice; for what can proceed from mortal man but what is abominable before God? Our prayers must therefore be sanctified in order that they please God; and the only way of sanctification is through the sacrifice of Christ. When they offered sacrifices under the law they also joined prayers; and by this ceremony they who made any request professed themselves unworthy except a sacrifice was offered. The Prophet then mentions here what God had commanded under the law, but he shews that hypocrites separated the principal thing from the external signs. God indeed neither disregards nor rejects signs, but when what they signify is separated from them, there is then an intolerable profanation. Let us then know, that though nothing may be wanting in the external worship, yet whatever we seek to do is abominable to God except it be accompanied with sincerity of heart.

But I will consume them, he says, with the sword, and with famine, and with pestilence I render the particle כי ki, “but.” He refers here to three modes of destruction, that the Jews might surely know that they were to perish, according to what is said elsewhere, “He who escapes from the sword shall perish by the famine, and he who survives the famine shall perish by the pestilence.” God shews, in short, that he was armed with various kinds of punishment, so that they who had so provoked him as wholly to lose the hope of pardon, could by no escapes deliver themselves from destruction. God might indeed have consumed the Jews by one punishment, he might have also threatened them in general terms without specifying anything, but as the unbelieving ever promise themselves some way of escape, so his purpose was to hold them bound in every way, that they might know that they were shut up on every side, and that no way of escape could be found. This is the meaning. It follows —
