2. It not only removes the hinderances of reason, but positively helps reason. It makes even the speculative notions the more lively. It engages the attention of the mind, with the more fixedness and intenseness to that kind of objects; which causes it to have a clearer view of them, and enables it more clearly to see their mutual relations, and occasions it to take more notice of them. The ideas themselves that otherwise are dim and obscure are by this means impressed with the greater strength, and have a light cast upon them; so that the mind can better judge of them: as he that beholds the objects on the face of the earth, when the light of the sun is cast upon them, is under greater advantage to discern them in their true forms and mutual relations than he that sees them in a dim starlight or twilight.
The mind having a sensibleness of the excellency of divine objects, dwells upon them with delight; and the powers of the soul are more awakened and enlivened to employ themselves in the contemplation of them, and exert themselves more fully and much more to the purpose. The beauty and sweetness of the objects draws on the faculties, and draws forth their exercises: so that reason itself is under far greater advantages for its proper and free exercises, and to attain its proper end, free of darkness and delusion. But,
Secondly, A true sense of the divine excellency of the things of God’s word doth more directly and immediately convince of the truth of them; and that because the excellency of these things is so superlative. There is a beauty in them that is so divine and godlike, that is greatly and evidently distinguishing of them from things merely human, or that men are the inventors and authors of; a glory that is so high and great that, when clearly seen, commands assent to their divinity and reality. When there is an actual and lively discovery of this beauty and excellency, it won’t allow of any such thought as that it is a human work, or the fruit of men’s invention. This evidence that they that are spiritually enlightened have of the truth of the things of religion is a kind of intuitive and immediate evidence. They believe the doctrines of God’s word to be divine, because they see divinity in them; i.e., they see a divine, and transcendent, and most evidently distinguishing glory in them; such a glory as, if clearly seen, does not leave room to doubt of their being of God, and not of men.
Such a conviction of the truth of religion as this, arising, these ways, from a sense of the divine excellency of them, is that true spiritual conviction that there is in saving faith. And this original of it is that by which it is most essentially distinguished from that common assent which unregenerate men are capable of.
II. I proceed now to the second thing proposed, viz., to show how this light is immediately given by God, and not obtained by natural means. And here,
1. ’Tis not intended that the natural faculties are not made use of in it. The natural faculties are the subject of this light: and they are the subject in such a manner that they are not merely passive, but active in it; the acts and exercises of man’s understanding are concerned and made use of in it. God, in letting in this light into the soul, deals with man according to his nature, or as a rational creature; and makes use of his human faculties. But yet this light is not the less immediately from God for that; though the faculties are made use of, ’tis as the subject and not as the cause; and that acting of the faculties in it is not the cause, but is either implied in the thing itself (in the light that is imparted) or is the consequence of it: as the use that we make of our eyes in beholding various objects, when the sun arises, is not the cause of the light that discovers those objects to us.
2. ’Tis not intended that outward means have no concern in this affair. As I have observed already, ’tis not in this affair, as it is in inspiration, where new truths are suggested: for here is by this light only given a due apprehension of the same truths that are revealed in the word of God; and therefore it is not given without the word. The gospel is made use of in this affair: this light is the “light of the glorious gospel of Christ,” 2 Cor. iv. 4. The gospel is as a glass, by which this light is conveyed to us, 1 Cor. xiii. 12: “Now we see through a glass.”—But,
3. When it is said that this light is given immediately by God, and not obtained by natural means, hereby is intended, that ’tis given by God without making use of any means that operate by their own power, or a natural force. God makes use of means; but ’tis not as mediate causes to produce this effect. There are not truly any second causes of it; but it is produced by God immediately. The word of God is no proper cause of this effect: it does not operate by any natural force in it. The word of God is only made use of to convey to the mind the subject matter of this saving instruction: and this indeed it doth convey to us by natural force or influence. It conveys to our minds these and those doctrines; it is the cause of the notion of them in our heads, but not of the sense of the divine excellency of them in our hearts. Indeed a person can’t have spiritual light without the word. But that don’t argue that the word properly causes that light. The mind can’t see the excellency of any doctrine, unless that doctrine be first in the mind; but the seeing of the excellency of the doctrine may be immediately from the Spirit of God; though the conveying of the doctrine or proposition itself may be by the word. So that the notions that are the subject matter of this light are conveyed to the mind by the word of God; but that due sense of the heart, wherein this light formally consists, is immediately by the Spirit of God. As for instance, that notion that there is a Christ, and that Christ is holy and gracious, is conveyed to the mind by the word of God: but the sense of the excellency of Christ by reason of that holiness and grace, is nevertheless immediately the work of the Holy Spirit.—I come now,
III. To show the truth of the doctrine; that is, to show that there is such a thing as that spiritual light that has been described, thus immediately let into the mind by God. And here I would show briefly, that this doctrine is both scriptural and rational.
First, ’Tis scriptural. My text is not only full to the purpose, but ’tis a doctrine that the Scripture abounds in. We are there abundantly taught that the saints differ from the ungodly in this, that they have the knowledge of God, and a sight of God, and of Jesus Christ. I shall mention but few texts of many. 1 John iii. 6, “Whosoever sinneth hath not seen him, nor known him.” 3 John 11, “He that doeth good is of God: but he that doeth evil hath not seen God.” John xiv. 19, “The world seeth me no more; but ye see me.” John xvii. 3, “And this is eternal life, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.” This knowledge, or sight of God and Christ, can’t be a mere speculative knowledge; because it is spoken of as a seeing and knowing wherein they differ from the ungodly. And by these Scriptures it must not only be a different knowledge in degree and circumstances, and different in its effects; but it must be entirely different in nature and kind.
