Притчи 15:13

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.

15:13 What people feel affects how they present themselves (cp. 15:30).
