_Direct._ XIV. Take heed lest the secret prevalency of carnal ends or interest, and of fleshly wisdom, do bias your judgment, and make you stretch your consciences to take those vows or promises, which otherwise you would judge unlawful, and refuse. Never good cometh by following the reasonings and interest of the flesh, even in smaller matters; much less in cases of such great importance. Men think it fitteth them at the present, and doth the business which they feel most urgent; but it payeth them home with troubles and perplexities at the last: it is but like a draught of cold water in a fever. You have some present char to do, or some strait to pass through, in which you think that such an oath, or promise, or profession would much accommodate you; and therefore you venture on it, perhaps to your perdition. It is a foolish course to cure the parts (yea, the more ignoble parts) with the neglect and detriment of the whole: it is but like those that cure the itch by anointing themselves with quicksilver; which doth the char for them, and sendeth them after to their graves, or casteth them into some far worse disease. Remember how deceitful a thing the heart is, and how subtly such poison of carnal ends will insinuate itself. Oh how many thousands hath this undone! that before they are aware, have their wills first charmed and inclined to the forbidden thing, and fain would have it to be lawful; and then have brought themselves to believe it lawful, and so to commit the sin; and next to defend it, and next to become the champions of Satan, to fight his battles, and vilify and abuse them, that by holy wisdom and tenderness have kept themselves from the deceit. _Tit. 2.

I shall show it you in part in these particulars. [Sidenote: The heinousness of perjury.]
