The Gospel - All of Grace

1. Man cannot understand it. This is necessary to a change. Whatsoever is done by the will, must be done by the impulse of some other faculty. Sensitive appetite cannot instruct the will to this work. Sense is not capable of reason, much less of religion, though it be the portal to both. The will can never be moved to any good thing, unless the mind propound it as good and amiable. The act of thinking must precede the act of believing, for we cannot believe without thinking of what we believe. It is less to think than understand. If we cannot, then, do that which is less in the preparation, we cannot do that which is greater, especially when it is impossible to will without thinking; and thinking is a necessary means to willing. He that cannot prepare himself for a good thought, how can he prepare himself for a gracious habit? What ability have we to the act of faith, when we have no ability to any thought of faith? We cannot by the strength of nature understand it, if we consider,

(1.) The first blot caused by sin was upon the understanding. Man was first deceived by the sophistical reasonings of the serpent. The first effect of sin was to spread a thick darkness upon Adam's understanding. Though the whole house, and every beam of it, fell together, yet this faculty was first unfastened, and brought all the rest to ruin. As soon as ever he ceased from glorifying God as God, a darkness was brought upon his foolish heart: Rom. i. 21, 'When they knew God, they glorified him not as God, but became vain in their imaginations, and their foolish heart was darkened,' where the apostle describes the state of man in corrupt nature after his fall.

(2.) There is a darkness transmitted from him to the understanding of every man by nature. The light is darkened in the heaven of the soul, the more spiritual part of the mind, Isa. v. 30, as the prophet speaks in another case. Our understandings are so closed up with the thick slime of sin, that we cannot see the beauty of gospel truths; 'darkness comprehends not the light,' John i. 5. Though the light of the sun did shine a thousand times brighter than it does, and strike upon the face and eyelids of a man with the greatest glory, yet if there be a spot upon the apple of his eye, if he scants a seeing faculty, he can apprehend nothing of it.

(3.) There is an unsuitableness and a contrariety in the mind of man to the gospel, which is the instrument of regeneration. There is a mighty distance between the spiritual object and the natural faculty. The understanding, though never so well furnished with natural stuff, is but natural, and flesh; the object is supernatural and spiritual; therefore the richest mere nature can no more attain to the knowledge of spiritual things, than the clearest sense can attain to the knowledge of rational. Though every man 'by nature has the things contained in the law,' Rom. ii. 14, 15, yet no man has by nature the things contained in the gospel. The gospel has not the same advantage in the hearts of men as the law hash, for it finds nothing of kin to it. Though a natural heart has some broken pieces of the law of God deposited in it, yet there is not the least syllable of Christ or regeneration written in the mind by the hand of nature.

(4.) Besides this, the natural levity of the understanding does incapacitate it to prepare itself. It is with the understanding as with a line, the farther it is stretched out the weaker and more wavering it is. So is the understanding, being at a distance from God. How do vain thoughts intrude into the mind! No man can keep a door locked against them. We feel them rushing upon us while we endeavour to avoid them. We are confounded and overwhelmed by them, and drawn to things against our own resolutions. Man has not the command of his own heart, so much as to think steadily of a divine object.

(5.) Hence it follows that a natural mind has no right notion of grace. To the right notion of a thing is required suitableness, pleasure, and a fixedness of the mind upon it. A natural mind wants all these. How can it then prepare itself for that which it has no knowledge of? And without knowledge it cannot commend it to the will. The apostle asserts a plain cannot in this business: 1 Cor. ii. 14, 'He cannot know them, because they are spiritually discerned.' Being destitute of the Spirit, they cannot discern the things of the Spirit.
