15 The simple believeth every word: but the prudent man looketh well to his going.

      Note, 1. It is folly to be credulous, to heed every flying report, to give ear to every man's story, though ever so improbable, to take things upon trust from common fame, to depend upon every man's profession of friendship and give credit to every one that will promise payment; those are simple who thus believe every word, forgetting that all men, in some sense, are liars in comparison with God, all whose words we are to believe with an implicit faith, for he cannot lie. 2. It is wisdom to be cautious: The prudent man will try before he trusts, will weigh both the credibility of the witness and the probability of the testimony, and then give judgment as the thing appears or suspend his judgment till it appears. Prove all things, and believe not every spirit.

      16 A wise man feareth, and departeth from evil: but the fool rageth, and is confident.

      Note, 1. Holy fear is an excellent guard upon every holy thing, and against every thing that is unholy. It is wisdom to depart from evil, from the evil of sin, and thereby from all other evil; and therefore it is wisdom to fear, that is, to be jealous over ourselves with a godly jealousy, to keep up a dread of God's wrath, to be afraid of coming near the borders of sin or dallying with the beginnings of it. A wise man, for fear of harm, keeps out of harm's way, and starts back in a fright when he finds himself entering into temptation. 2. Presumption is folly. He who, when he is warned of his danger, rages and is confident, furiously pushes on, cannot bear to be checked, bids defiance to the wrath and curse of God, and, fearless of danger, persists in his rebellion, makes bold with the occasions of sin, and plays upon the precipice, he is a fool, for he acts against his reason and his interest, and his ruin will quickly be the proof of his folly.

      12 A prudent man foreseeth the evil, and hideth himself; but the simple pass on, and are punished.

      This we had before, ch. xxii. 3. Note, 1. Evil may be foreseen. Where there is temptation, it is easy to foresee that if we thrust ourselves into it there will be sin, and as easy to foresee that if we venture upon the evil of sin there will follow the evil of punishment; and, commonly, God warns before he wounds, having set watchmen over us, Jer. vi. 17. 2. It will be well or ill with us according as we do or do not improve the foresight we have of evil before us: The prudent man, foreseeing the evil, forecasts accordingly, and hides himself, but the simple is either so dull that he does not foresee it or so wilful and slothful that he will take no care to avoid it, and so he passes on securely and is punished. We do well for ourselves when we provide for hereafter.
