It is expedient then that the understanding should be occupied in prayer, as well as the heart and mouth: “I will pray with the Spirit, and I will pray with the understanding also.” That which is done with understanding, is done more effectually, sensibly, and heartily, as I shall show farther anon, than that which is done without it; which made the apostle pray for the Colossians, that God would fill them “with the knowledge of his will, in all wisdom and spiritual understanding” (Col 1:9). And for the Ephesians, that God would give unto them “the spirit of wisdom and revelation, in the knowledge of him” (Eph 1:17). And so for the Philippians, that God would make them abound “in knowledge, and in all judgment” (Phil 1:9). A suitable understanding is good in everything a man undertakes, either civil or spiritual; and therefore it must be desired by all them that would be a praying people. In my speaking to this, I shall show you what it is to pray with understanding.

Understanding is to be taken both for speaking in our mother-tongue, and also experimentally. I pass the first, and treat only on the second.

For the making of right prayers, it is to be required that there should be a good or spiritual understanding in all them who pray to God.

First. To pray with understanding, is to pray as being instructed by the Spirit in the understanding of the want of those things which the soul is to pray for. Though a man be in never so much need of pardon of sin, and deliverance from wrath to come, yet if he understand not this, he will either not desire them at all, or else be so cold and lukewarm in his desires after them, that God will even loathe his frame of spirit in asking for them. Thus it was with the church of the Laodiceans, they wanted knowledge or spiritual understanding; they knew not that they were poor, wretched, blind, and naked. The cause whereof made them, and all their services, so loathsome to Christ, that he threatens to spew them out of his mouth (Rev 3:16, 17). Men without understanding may say the same words in prayer as others do; but if there be an understanding in the one, and none in the other, there is, O there is a mighty difference in speaking the very same words! The one speaking from a spiritual understanding of those things that he in words desires, and the other words it only, and there is all.

Second. Spiritual understanding espieth in the heart of God a readiness and willingness to give those things to the soul that it stands in need of. David by this could guess at the very thoughts of God towards him (Psa 40:5). And thus it was with the woman of Canaan; she did by faith and a right understanding discern, beyond all the rough carriage of Christ, tenderness and willingness in his heart to save, which caused her to be vehement and earnest, yea, restless, until she did enjoy the mercy she stood in need of (Matt 15:22-28).

And understanding of the willingness that is in the heart of God to save sinners, there is nothing will press the soul more to seek after God, and to cry for pardon, than it. If a man should see a pearl worth an hundred pounds lie in a ditch, yet if he understood not the value of it, he would lightly pass it by: but if he once get the knowledge of it, he would venture up to the neck for it. So it is with souls concerning the things of God: if a man once get an understanding of the worth of them, then his heart, nay, the very strength of his soul, runs after them, and he will never leave crying till he have them. The two blind men in the gospel, because they did certainly know that Jesus, who was going by them, was both able and willing to heal such infirmities as they were afflicted with: therefore they cried, and the more they were rebuked, the more they cried (Matt 20:29-31).

Third. The understanding being spiritually enlightened, hereby there is the way, as aforesaid, discovered, through which the soul should come unto God; which gives great encouragement unto it. It is else with a poor soul, as with one who hath a work to do, and if it be not done, the danger is great; if it be done, so is the advantage. But he knows not how to begin, nor how to proceed; and so, through discouragement, lets all alone, and runs the hazard.

Fourth. The enlightened understanding sees largeness enough in the promises to encourage it to pray; which still adds to it strength to strength. As when men promise such and such things to all that will come for them, it is great encouragement to those that know what promises are made, to come and ask for them.

Fifth. The understanding being enlightened, way is made for the soul to come to God with suitable arguments, sometimes in a way of expostulation, as Jacob (Gen 32:9). Sometimes in way of supplication, yet not in a verbal way only, but even from the heart there is forced by the Spirit, through the understanding, such effectual arguments as moveth the heart of God. When Ephraim gets a right understanding of his own unseemly carriages towards the Lord, then he begins to bemoan himself (Jer 31:18-20). And in bemoaning of himself, he used such arguments with the Lord, that it affects his heart, draws out forgiveness, and makes Ephraim pleasant in his eyes through Jesus Christ our Lord: “I have surely heard Ephraim bemoaning himself thus,” saith God, “Thou hast chastised me, and I was chastised; as a bullock unaccustomed to the yoke; turn thou me, and I shall be turned; for thou art the Lord my God. Surely after that I was turned, I repented, and after that I was instructed,” or had a right understanding of myself, “I smote upon my thigh, I was ashamed; yea, even confounded; because I did bear the reproach of my youth.” These be Ephraim’s complaints and bemoanings of himself; at which the Lord breaks forth into these heart-melting expressions, saying, “Is Ephraim my dear son? Is he a pleasant child? For since I spake against him, I do earnestly remember him still; therefore my bowels are troubled for him; I will surely have mercy upon him, saith the Lord.” Thus, you see, that as it is required to pray with the Spirit, so it is to pray with the understanding also. And to illustrate what hath been spoken by a similitude:—set the case, there should come two a-begging to your door; the one is a poor, lame, wounded, and almost starved creature, the other is a healthful lusty person; these two use the same words in their begging; the one saith he is almost starved, so doth the other: but yet the man that is indeed the poor, lame, or maimed person, he speaks with more sense, feeling, and understanding of the misery that is mentioned in their begging, than the other can do; and it is discovered more by his affectionate speaking, his bemoaning himself. His pain and poverty make him speak more in a spirit of lamentation than the other, and he shall be pitied sooner than the other, by all those that have the least dram of natural affection or pity. Just thus it is with God: there are some who out of custom and formality go and pray; there are others who go in the bitterness of their spirits: the one he prays out of bare notion and naked knowledge; the other hath his words forced from him by the anguish of his soul. Surely that is the man that God will look at, “even to him that is poor,” of an humble “and of a contrite spirit, and trembleth at my word” (Isa 66:2).

Sixth. An understanding well enlightened is of admirable use also, both as to the matter and manner of prayer. He that hath his understanding well exercised, to discern between good and evil, and in it placed a sense either of the misery of man, or the mercy of God; that soul hath no need of the writings of other men to teach him by forms of prayer. For as he that feels the pain needs not to be taught to cry O! even so he that hath his understanding opened by the Spirit needs not so to be taught of other men’s prayers, as that he cannot pray without them. The present sense, feeling, and pressure that lieth upon his spirit, provokes him to groan out his request unto the Lord. When David had the pains of hell catching hold on him, and the sorrows of hell compassing him about, he needs not a bishop in a surplice to teach him to say, “O Lord, I beseech thee, deliver my soul” (Psa 116:3, 4). Or to look into a book, to teach him in a form to pour out his heart before God. It is the nature of the heart of sick men, in their pain and sickness, to vent itself for ease, by dolorous groans and complainings to them that stand by. Thus it was with David, in Psalm 38:1-12. And thus, blessed be the Lord, it is with them that are endued with the grace of God.
