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.
