Here, 1. Harmless mirth is recommended to us, as that which contributes to the health of the body, making men lively and fit for business, and to the acceptableness of the conversation, making the face to shine and rendering us pleasant one to another. A cheerful spirit, under the government of wisdom and grace, is a great ornament to religion, puts a further lustre upon the beauty of holiness, and makes men the more capable of doing good. 2. Hurtful melancholy is what we are cautioned against, as a great enemy to us, both in our devotion and in our conversation: By sorrow of the heart, when it has got dominion and plays the tyrant, as it will be apt to do it if be indulged awhile, the spirit is broken and sunk, and becomes unfit for the service of God. The sorrow of the world works death. Let us therefore weep as though we wept not, in justice to ourselves, as well as in conformity to God and his providence.

A merry heart maketh a cheerful countenance,.... Or, a "joyful heart" (c); that is joyful in the God of its salvation; that rejoices in Christ Jesus; is filled with joy and peace through believing in him, in his person, blood, righteousness, and sacrifice; that has a comfortable view of his justification by his righteousness, of peace and pardon by his blood, of the atonement of his sins by his sacrifice; to whom he has said, "be of good cheer, thy sins are forgiven thee", Mat 9:2; who has peace in him, though tribulation in the world: as such a man's heart must be made glad, this will make his countenance cheerful, or cause him to lift up his head with joy; as it is in natural things, so it is in spiritual ones;

but by sorrow of the heart the spirit is broken; a man is dejected, his spirits sink, and it is seen in his countenance: there is a great sympathy between the body and mind, the one is much affected by the other; when the heart is full of sorrow, the animal spirits are low, the nerves are loosened, the whole frame, of nature is enfeebled, and the body emaciated; this is often the case through outward troubles (d): physicians say (e) that grief weakens the strength, and destroys the spirits, more than labour does. "The sorrow of the world worketh death", Co2 7:10; and sometimes, through spiritual troubles, a sense of sin and guilt of it, a legal sorrow, which produces a legal contrition of spirit; and such "a wounded spirit who can bear?" Pro 18:14. This is the effect of a mere work of the law upon the conscience; and stands opposed to the spiritual joy, and the effects of it, the Gospel brings.

spirit is broken--and so the countenance is sad.
