1. _Those convictions that natural men may have of their sin and misery_, is not _this_ spiritual and divine light. Men in a natural condition may have convictions of the guilt that lies upon them, and of the anger of God and their danger of divine vengeance. Such convictions are from light or sensibleness of truth. That some sinners have a greater conviction of their guilt and misery than others, is because some have more light, or more of an apprehension of truth than others. And this light and conviction may be from the Spirit of God; the Spirit convinces men of sin: but yet nature is much more concerned in it than in the communication of that spiritual and divine light that is spoken of in the doctrine; 'tis from the Spirit of God only as assisting natural principles, and not as infusing any new principles. Common grace differs from special, in that it influences only by assisting of nature; and not by imparting grace, or bestowing anything above nature. The light that is obtained is wholly natural, or of no superior kind to what mere nature attains to, though more of that kind be obtained than would be obtained if men were left wholly to themselves: or, in other words, common grace only assists the faculties of the soul to do that more fully which they do by nature, as natural conscience or reason will, by mere nature, make a man sensible of guilt, and will accuse and condemn him when he has done amiss. Conscience is a principle natural to men; and the work that it doth naturally, or of itself, is to give an apprehension of right and wrong, and to suggest to the mind the relation that there is between right and wrong and a retribution. The Spirit of God, in those convictions which unregenerate men sometimes have, assists conscience to do this work in a further degree than it would do if they were left to themselves: he helps it against those things that tend to stupefy it, and obstruct its exercise. But in the renewing and sanctifying work of the Holy Ghost, those things are wrought in the soul that are above nature, and of which there is nothing of the like kind in the soul by nature; and they are caused to exist in the soul habitually, and according to such a stated constitution or law that lays such a foundation for exercises in a continued course, as is called a principle of nature. Not only are remaining principles assisted to do their work more freely and fully, but those principles are restored that were utterly destroyed by the fall; and the mind thenceforward habitually exerts those acts that the dominion of sin had made it as wholly destitute of, as a dead body is of vital acts.
