Rule I.
See that the persuasion and assurance hereof which you look after and desire be regular, and not such as is suited merely unto your own imaginations. Our second and third general rules about the nature of all spiritual assurance, and what is consistent therewithal, are here to be taken into consideration. If you look to have such an evidence, light into, and absolute conviction of, this matter, as shall admit of no doubts, fears, questionings, just occasions and causes of new trials, teachings, and self-examinations, you will be greatly deceived. Regeneration induceth a new principle into the soul, but it doth not utterly expel the old; some would have security, not assurance. The principle of sin and unbelief will still abide in us, and still work in us. Their abiding and their acting must needs put the soul upon a severe inquiry, whether they are not prevalent in it beyond what the condition of regeneration will admit. The constant conflicts we must have with sin will not suffer us to have always so clear an evidence of our condition as we would desire. Such a persuasion as is prevalent against strong objections to the contrary, keeping up the heart to a due performance of those duties in faith which belong unto the state of regeneration, is the substance of what in this kind you are to look after.
