Here is, I. An account of four things that are unsearchable, too wonderful to be fully known. And here,

1. The first three are natural things, and are only designed as comparisons for the illustration of the last. We cannot trace, (1.) An eagle in the air. Which way she has flown cannot be discovered either by the footstep or by the scent, as the way of a beast may upon ground; nor can we account for the wonderful swiftness of her flight, how soon she has gone beyond our ken. (2.) A serpent upon a rock. The way of a serpent in the sand we may find by the track, but not of a serpent upon the hard rock; nor can we describe how a serpent will, without feet, in a little time creep to the top of a rock. (3.) A ship in the midst of the sea. The leviathan indeed makes a path to shine after him, one would think the deep to be hoary (Job 41:32), but a ship leaves no mark behind it, and sometimes it is so tossed upon the waves that one would wonder how it lives at sea and gains its point. The kingdom of nature is full of wonders, marvellous things which the God of nature does, past finding out.

2. The fourth is a mystery of iniquity, more unaccountable than any of these; it belongs to the depths of Satan, that deceitfulness and that desperate wickedness of the heart which none can know, Jer. 17:9. It is twofold:—(1.) The cursed arts which a vile adulterer has to debauch a maid, and to persuade her to yield to his wicked and abominable lust. This is what a wanton poet wrote a whole book of, long since, Deut. arte amandi—On the art of love. By what pretensions and protestations of love, and all its powerful charms, promises of marriage, assurances of secresy and reward, is many an unwary virgin brought to sell her virtue, and honour, and peace, and soul, and all to a base traitor; for so all sinful lust is in the kingdom of love. The more artfully the temptation is managed the more watchful and resolute ought every pure heart to be against it. (2.) The cursed arts which a vile adulteress has to conceal her wickedness, especially from her husband, from whom she treacherously departs; so close are her intrigues with her lewd companions, and so craftily disguised, that it is as impossible to discover her as to track an eagle in the air. She eats the forbidden fruit, after the similitude of Adam’s transgression, and then wipes her mouth, that it may not betray itself, and with a bold and impudent face says, I have done no wickedness. [1.] To the world she denies the fact, and is ready to swear it that she is as chaste and modest as any woman, and never did the wickedness she is suspected of. Those are the works of darkness which are industriously kept from coming to the light. [2.] To her own conscience (if she have any left) she denies the fault, and will not own that that great wickedness is any wickedness at all, but an innocent entertainment. See Hos. 12:7, 8. Thus multitudes ruin their souls by calling evil good and out-facing their convictions with a self-justification.

II. An account of four things that are intolerable, that is, four sorts of persons that are very troublesome to the places where they live and the relations and companies they are in; the earth is disquieted for them, and groans under them as a burden it cannot bear, and they are all much alike:—1. A servant when he is advanced, and entrusted with power, who is, of all others, most insolent and imperious; witness Tobiah the servant, the Ammonite, Neh. 2:10. 2. A fool, a silly, rude, boisterous, vicious man, who when he has grown rich, and is partaking of the pleasures of the table, will disturb all the company with his extravagant talk and the affronts he will put upon those about him. 3. An ill-natured, cross-grained, woman, when she gets a husband, one who, having made herself odious by her pride and sourness, so that one would not have thought any body would ever love her, yet, if at last she be married, that honourable estate makes her more intolerably scornful and spiteful than ever. It is a pity that that which should sweeten the disposition should have a contrary effect. A gracious woman, when she is married, will be yet more obliging. 4. An old maid-servant that has prevailed with her mistress, by humouring her, and, as we say, getting the length of her foot, to leave her what she has, or is as dear to her as if she was to be her heir, such a one likewise will be intolerably proud and malicious, and think all too little that her mistress gives her, and herself wronged if any thing be left from her. Let those therefore whom Providence has advanced to honour from mean beginnings carefully watch against that sin which will most easily beset them, pride and haughtiness, which will in them, of all others, be most insufferable and inexcusable; and let them humble themselves with the remembrance of the rock out of which they were hewn.
