suffered it to abide in power and prevalency, without attempting
mortification will not do it.
You will say, "What are these dangerous marks and symptoms, the desperate attendancies of an indwelling lust, that you intend?" Some of them I shall name:--
1. Inveterateness.-- If it hath lain long corrupting in thy heart, if thou hast suffered it to abide in power and prevalency, without attempting vigorously the killing of it, and the healing of the wounds by it, for some long season, thy distemper is dangerous. Hast thou permitted worldliness, ambition, greediness of study, to eat up other duties, the duties wherein thou oughtest to hold constant communion with God, for some long season? or uncleanness to defile thy heart with vain, and foolish, and wicked imaginations for many days? Thy lust hath a dangerous symptom. So was the case with David: Ps. 38:5, "My wounds stink and are corrupt because of my foolishness." When a lust hath lain long in the heart, corrupting, festering, cankering, it brings the soul to a woful condition. In such a case an ordinary course of humiliation will not do the work: whatever it be, it will by this means insinuate itself more or less into all the faculties of the soul, and habituate the affections to its company and society; it grows familiar to the mind and conscience, that they do not startle at it as a strange thing, but are bold with it as that which they are wonted unto; yea, it will get such advantage by this means as oftentimes to exert and out forth itself without having any notice taken of it at all, as it seems to have been with Joseph in his swearing by the life of Pharoah. Unless some extraordinary course be taken, such a person hath no ground in the world to expect that his latter end shall be peace.
For, first, How will he be able to distinguish between the long abode of an unmortified lust and the dominion of sin, which cannot befall a regenerate person? Secondly, How can he promise himself that it shall ever be otherwise with him, or that his lust will cease tumultuating and seducing, when he sees it fixed and abiding, and hath done so for many days, and hath gone through a variety of conditions with him? It may be it hath tried mercies and afflictions, and those possibly so remarkable that the soul could not avoid the taking special notice of them; it may be it hath weathered out many a storm, and passed under much variety of gifts in the administration of the word; and will it prove an easy thing to
