Now that we may be able to determine whether our want of assurance proceeds from some natural cause or bodily distemper, we must enquire; whether, before this, we have endeavoured to walk in all good conscience in the sight of God? to hate every false way, and make religion the great business of life, so that we cannot assign any reigning sin as the cause of our present desponding frame? And also, whether we have been diligent in performing the duty of self-examination, and have been sensible that we stood in need of the Spirit’s witness with ours, in order to our arriving to a comfortable persuasion that we are in a state of grace? And if, as the result of these enquiries, we cannot see any cause leading to this dejection of spirit, but the unavoidable infirmities, which we are daily liable to, then we may probably conclude, that it arises from a distemper of body. And, in order to our determining this matter, we must farther inquire; whether some afflictive providence has not had an influence upon us, to bring us into a melancholy temper? and whether this does not appear in what relates to our secular, as well as our spiritual concerns? and if this be the case, though it be very afflictive, it is not attended with that guilt as it would be, had it been occasioned by some presumptuous sin; and there are other medicines to be used when it arises from this cause, besides those which are of a spiritual nature, that are contained in the gospel; but what they are, it is not our business, in this place, to determine. (2.) There are many sins which are the occasion of a person’s being destitute of assurance. As all the troubles of life are brought upon us by sin; so are all our doubts and fears, arising from the want of a comfortable sense of, or interest in, the love of God. It pleases God, in the method of his providence, thus to deal with his people, that he may humble them for presumptuous sins; more especially those that are committed against light and conviction of conscience, that he may bring to remembrance their sins of omission, or neglect to exercise those graces in which the life of faith consists, that hereby they may feel the effect of their stupidity, indifferency, and carnal security, or their engaging in religious duties, in their own strength, without dependence on the Spirit and grace of God, or a due sense of their inability to perform any duty in a right way. Or, sometimes, as has been before observed, they want assurance, because they do not examine themselves, which is God’s ordinance for the attaining this privilege; or, if they do, they neglect to give that glory to the Holy Spirit which is due to him, by depending on his enlightening influence, whereby they may arrive to a comfortable persuasion of their interest in Christ.
