13 He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.

      Here is, 1. The folly of indulging sin, of palliating and excusing it, denying or extenuating it, diminishing it, dissembling it, or throwing the blame of it upon others: He that thus covers his sins shall not prosper, let him never expect it. He shall not succeed in his endeavour to cover his sin, for it will be discovered, sooner or later. There is nothing hid which shall not be revealed. A bird of the air shall carry the voice. Murder will out, and so will other sins. He shall not prosper, that is, he shall not obtain the pardon of his sin, nor can he have any true peace of conscience. David owns himself to have been in a constant agitation while he covered his sins, Ps. xxxii. 3, 4. While the patient conceals his distemper he cannot expect a cure. 2. The benefit of parting with it, both by a penitent confession and a universal reformation: He that confesses his guilt to God, and is careful not to return to sin again, shall find mercy with God, and shall have the comfort of it in his own bosom. His conscience shall be eased and his ruin prevented. See 1 John i. 9; Jer. iii. 12, 13. When we set sin before our face (as David, My sin is ever before me) God casts it behind his back.

      14 Happy is the man that feareth alway: but he that hardeneth his heart shall fall into mischief.

      Here is, 1. The benefit of a holy caution. It sounds strangely, but it is very true: Happy is the man that feareth always. Most people think that those are happy who never fear; but there is a fear which is so far from having torment in it that it has in it the greatest satisfaction. Happy is the man who always keeps up in his mind a holy awe and reverence of God, his glory, goodness, and government, who is always afraid of offending God and incurring his displeasure, who keeps conscience tender and has a dread of the appearance of evil, who is always jealous of himself, distrustful of his own sufficiency, and lives in expectation of troubles and changes, so that, whenever they come, they are no surprise to him. He who keeps up such a fear as this will live a life of faith and watchfulness, and therefore happy is he, blessed and holy. 2. The danger of a sinful presumption: He that hardens his heart, that mocks at fear, and sets God and his judgments at defiance, and receives not the impressions of his word or rod, shall fall into mischief; his presumption will be his ruin, and whatever sin (which is the greatest mischief) he falls into it is owing to the hardness of his heart.
