Proverbs 15:7-13

The lips of the wise disperse knowledge: but the heart of the foolish doeth not so. The sacrifice of the wicked is an abomination to the LORD: but the prayer of the upright is his delight. The way of the wicked is an abomination unto the LORD: but he loveth him that followeth after righteousness. Correction is grievous unto him that forsaketh the way: and he that hateth reproof shall die. Hell and destruction are before the LORD: how much more then the hearts of the children of men? A scorner loveth not one that reproveth him: neither will he go unto the wise. A merry heart maketh a cheerful countenance: but by sorrow of the heart the spirit is broken.

I should apprehend that the mirth here spoken of, means the true joy of the soul, arising from the consciousness of being at peace with God. There can be no mirth, no real comfort while the soul is at enmity with God by wicked works. Solomon hath expressed his sense of this passage, I apprehend, in another, where he saith, Go thy way, eat thy bread with joy, and drink thy wine with a merry heart, for God now accepteth thy works. Yes! a soul accepted in Jesus, may indeed both eat and drink the common bread and water, for the body's sustenance, with joy, and the sacred bread and wine, in token of communion with Jesus, for the soul's health, with delight, when brought nigh by the blood of the cross! Here is a solid foundation for the most heart-felt joy, and for making the countenance always cheerful. Ecclesiastes 9:7.
