1. It has been the endeavour of Satan, from the beginning of the world, to put asunder what God hath joined together; to separate inward from outward religion; to set one of these at variance with the other. And herein he has met with no small success among those who were "ignorant of his devices."

Many, in all ages, having a zeal for God, but not according to knowledge, have been strictly attached to the "righteousness of the law," the performance of outward duties, but in the mean time wholly regardless of inward righteousness, "the righteousness which is of God by faith." And many have run into the opposite extreme, disregarding all outward duties, perhaps even "speaking evil of the law, and judging the law," so far as it enjoins the performance of them.

2. It is by this very device of Satan, that faith and works have been so often set at variance with each other. And many who had a real zeal for God have, for a time, fallen into the snare on either hand. Some have magnified faith to the utter exclusion of good works, not only from being the cause of our justification, (for we know that man is justified freely by the redemption which is in Jesus,) but from being the necessary fruit of it, yea, from having any place in the religion of Jesus Christ. Others, eager to avoid this dangerous mistake, have run as much too far the contrary way; and either maintained that good works were the cause, at least the previous condition, of justification, -- or spoken of them as if they were all in all, the whole religion of Jesus Christ.

3. In the same manner have the end and the means of religion been set at variance with each other. Some well-meaning men have seemed to place all religion in attending the Prayers of the Church, in receiving the Lord's supper, in hearing sermons, and reading books of piety; neglecting, mean time, the end of all these, the love of God and their neighbour. And this very thing has confirmed others in the neglect, if not contempt, of the ordinances of God, -- so wretchedly abused to undermine and overthrow the very end they were designed to establish.

. . .

II. 3. Another reason or ground of fasting is this: Many of those who now fear God are deeply sensible how often they have sinned against him, by the abuse of these lawful things. They know how much they have sinned by excess of food; how long they have transgressed the holy law of God, with regard to temperance, if not sobriety too; how they have indulged their sensual appetites, perhaps to the impairing even their bodily health, -- certainly to the no small hurt of their soul For hereby they continually fed and increased that sprightly folly, that airiness of mind, that levity of temper, that gay inattention to things of the deepest concern, that giddiness and carelessness of spirit, which were no other than drunkenness of soul, which stupefied all their noblest faculties, no less than excess of wine or strong drink. To remove, therefore, the effect, they remove the cause. They keep at a distance from all excess. They abstain, as far as is possible, from what had well nigh plunged them in everlasting perdition. They often wholly refrain; always take care to be sparing and temperate in all things.

4. They likewise well remember how fulness of bread increased not only carelessness and levity of spirit, but also foolish and unholy desires, yea, unclean and vile affections. And this experience puts beyond all doubt. Even a genteel, regular sensuality is continually sensualizing the soul, and sinking it into a level with the beasts that perish. It cannot be expressed what an effect variety and delicacy of food have on the mind as well as the body; making it just ripe for every pleasure of sense, as soon as opportunity shall invite. Therefore, on this ground also, every wise man will refrain his soul, and keep it low; will wean it more and more from all those indulgences of the inferior appetites, which naturally tend to chain it down to earth, and to pollute as well as debase it Here is another perpetual reason for fasting; to remove the food of lust and sensuality, to withdraw the incentives of foolish and hurtful desires, of vile and vain affections.

. . .

III. 2. "But is it not better" (as it has, Secondly, been objected) "to abstain from pride and vanity, from foolish and hurtful desires, from peevishness, and anger, and discontent, than from food?" Without question, it is. But here again we have need to remind you of our Lord's words: "These things ought ye to have done, and not to leave the other undone." And, indeed, the latter is only in order to the former; it is a means to that great end. We abstain from food with this view, -- that, by the grace of God conveyed into our souls through this outward means, in conjunction with all the other channels of his grace which he hath appointed, we may be enabled to abstain from every passion and temper which is not pleasing in his sight. We refrain from the one, that, being endued with power from on high, we may be able to refrain from the other. So that your argument proves just the contrary to what you designed. It proves that we ought to fast. For if we ought to abstain from evil tempers and desires, then we ought thus to abstain from food; since these little instances of self-denial are the ways God hath chose, wherein to bestow that great salvation.

IV. 1. I am, in the Last place, to show in what manner we are to fast, that it may be an acceptable service unto the Lord. And, First, let it be done unto the Lord, with our eye singly fixed on Him. Let our intention herein be this, and this alone, to glorify our Father which is in heaven; to express our sorrow and shame for our manifold transgressions of his holy law; to wait for an increase of purifying grace, drawing our affections to things above; to add seriousness and earnestness to our prayers; to avert the wrath of God, and to obtain all the great and precious promises which he hath made to us in Jesus Christ.
