There is a kind of indefinite religious feeling, which many mistake for Christian experience. They _feel_, and perhaps deeply; but they know not _why_ they feel. Such religious feeling is to be suspected as spurious. It may be the delusion of the devil. By persuading people to rest upon this spurious religious feeling, he accomplishes his purpose as well as if he had kept them in carnal security. And the clearer our views of truth, the more spiritual and holy will be our religious affections. Thus, godly sorrow arises from a sight of our own depravity, with a sense of the exceeding sinfulness of sin, as committed against a holy God, and against great light and mercy. Faith is produced by a spiritual view of the atonement of Christ, and of his infinite fulness as a complete and perfect Saviour. Love is excited by a discovery of the excellence of God's moral perfections. Holy fear and reverence arise from a sight of the majesty and glory of his natural attributes, and a sense of his presence. Joy may come from a sense of the infinite rectitude of his moral government; from the sight of the glory of God, in his works of providence and grace; or from a general view of the beauty and excellence of divine truth. Comfort may be derived from evidence of the divine favor; and confidence, from an appropriation of God's promises to ourselves. And in many other ways, also, the Holy Spirit produces spiritual feelings through the instrumentality of the truth. But all religious feeling, produced by impulse, without any rational view of the truth, is to be suspected. It may be the work of Satan, who is very busy in counterfeiting religious experiences for those he wishes to deceive. Every religious affection has its counterfeit. Thus, sorrow may be produced by the fear of hell, without any sense of the evil of sin; a presumption of our own good estate may be mistaken for faith, and this will produce joy; we may exercise a carnal or selfish love to God, because we think he loves us, and has made us the objects of his special favor; and the promises of God, so far as they concern the personal good of the believer, may administer as much comfort to the hypocrite as to the real saint. How exceedingly important is it, then, that you should not only exercise a general belief of the great doctrines of the gospel, but that you should have a right apprehension of them. The _truth_ is so necessary in the Christian warfare, that it is called the _sword of the Spirit_. But of what benefit is the sword to the soldier who knows not how to use it? The sword is used as much to ward off the blows of the enemy, as to attack him. But the novice, who should engage an enemy, without knowing the use of his weapon, would be thrust through in the first onset. Hence, the peculiar force of the prayer of our Lord, "Sanctify them through thy truth." It is by the use of the truth, as the "sword of the Spirit," in the Christian warfare, that the work of satisfaction is carried on.
