Charity and Its Fruits
their knowledge fails of being a saving knowledge, that it is only speculative and not practical. He that has a right and saving acquaintance with divine things, sees the excellency of holiness, and of all the ways of holiness, for he sees the beauty and excellency of God, which consist in his holiness; and, for the same reason, he sees the hatefulness of sin, and of all the ways of sin. And if a man knows the hatefulness of the ways of sin, certainly this tends to his avoiding these ways; and if he sees the loveliness of the ways of holiness, this tends to incline him to walk in them.
He that knows God, sees that he is worthy to be obeyed. Pharaoh did not see why he should obey God, because he did not know who he was, and therefore he says — "Who is the Lord, that I should obey his voice? I know not the Lord, neither will I let Israel go" (Exo. 5:2 ). This is signified to be the reason why wicked men work or practice iniquity, and carry themselves so wickedly, that they have no spiritual knowledge, as says the Psalmist — "Have all the workers of iniquity no knowledge? who eat up my people as they eat bread, and call not upon the Lord" (Psa. 14:4 ). And when God would describe the true knowledge of himself to the people of Israel, he does it by this fruit of it, that it led to holy practice — "He judged the cause of the poor and needy; then it was well with him. Was not this to know me? saith the Lord" (Jer. 22:16 ). And so the apostle John informs us that the keeping of Christ's commands is an infallible fruit of our knowing him; and he stigmatizes him as a gross hypocrite and liar who pretends that he knows Christ, and does not keep his commandments (1 John 2:3 , 4 ). If a man has spiritual knowledge and understanding, it tends to make him to be of an excellent spirit. "A man of understanding is of an excellent spirit" (Pro. 17:27 ). And such an excellent spirit will lead to a corresponding behavior. And the same appears, also,
5. From the more immediate consideration of the principle of grace itself, from which it will be seen that the tendency of all Christian grace is to practice. — And here,
First, it appears that all true Christian grace tends to practice, because the faculty which is the immediate seat of it is the faculty of the will, which is the faculty that commands all a man's actions and practice. The immediate seat of grace is in the will or disposition. And this shows that all true grace tends to practice; for there is not one of man's acts that can properly be said to belong to or to be any part of his practice, in any respect but that it is at the command of the will. When we speak of a man's practice, we have respect to those things that he does as a free and voluntary agent, or, which is the same thing, to those things that he does by an act of his will; so that the whole of a man's practice is directed by the faculty of the will. All the executive powers of the man, whether of body or mind, are subject to the faculty of the will by the constitution of Him who hath made man, and who is the great author of our being. The will is the fountain of the practice, as truly as the head of a spring is the fountain of the stream that flows from it. And, therefore, if a principle of true grace be seated in this faculty, it must necessarily tend to practice; as much as the flowing of water in the fountain tends to its flowing in the stream.
Second, it is the definition of grace, that it is a principle of holy action. What is grace but a principle of holiness, or a holy principle in the heart? But the word "principle" is relative to something, of which it is a principle. And if grace be a principle, what is it a principle of, but of action? Principles and actions are correlates, that necessarily have respect one to the other. Thus, the very idea of a principle of life is a principle that acts in the life. And so, when we speak of a principle of understanding, we mean a principle whence flow acts of understanding. And so by a principle of sin is meant a principle whence flow acts of sin. And, in the same manner, when we speak of a principle of grace, we mean a principle whence flow acts of grace, or gracious actions. A principle of grace has as much a relation to practice as a root has to the plant that it is the root of. If there be a root, it is the root of something; either the root of something that actually grows from it, or that tends to bring forth some plant. It is absurd to speak of a root that is the root of nothing; and so it is absurd to speak of a principle of grace that does not tend to grace in the practice.
Third, one more thing, by which that which is real and substantial is distinguished from that which is only a shadow or appearance, is, that it is effectual. A shadow or picture of a man, though it be ever so distinct or well drawn, or give ever so lively a representation, and though it be the picture of a very strong man, or even of a mighty giant, can do nothing. There is nothing accomplished and brought to pass by it, because it is not real, but only a shadow or image. The substance, or reality, however, is something that is effectual. And so it is with what is in the heart of man. That which is only an appearance or image of grace, though it looks like grace, is not effectual, because it wants reality and substance. But that which is real and substantial is effectual, and does indeed bring something to pass in the life. In other words, it acts itself out in practice. And so again,
Fourth, the nature of a principle of grace is to be a principle of life, or a vital principle. This we are everywhere taught in the Scriptures. There, natural men, who have no principle of grace in the heart, are represented as dead men, while those that have grace are represented as being alive, or having the principle of life in them. But it is the nature of a principle of life to be a principle of action and operation. A dead man does not act, or move, or bring anything to pass; but in living persons, the life appears by a continued course of action from day to day. They move, and walk, and work, and fill up their time with actions that are the fruits of life.
Fifth, true Christian grace is not only a principle of life, but an exceedingly powerful principle. Hence we read of "the power of godliness," as in 2 Tim. 3:5 ; and are taught that there is in it a divine power, such as was wrought in Christ when he was raised from the dead. But the more powerful any principle is, the more effectual it is to produce those operations and that practice to which it tends.
