“It is experience of ourselves, and finding what we are, that God commonly makes use of as the means of bringing us off from all dependence on ourselves. But men never get acquaintance with themselves so fast, as in the most earnest way of seeking [salvation]. They that are in this way have more to engage them to think of their sins, and strictly to observe themselves, and have much more to do with their own hearts, than others. Such a one has much more experience of his own weakness, than another that does not put forth and try his strength; and will therefore sooner see himself dead in sin. Such a one, though he hath a disposition continually to be flying to his own righteousness, yet finds rest in nothing; he wanders about from one thing to another, seeking something to ease his disquieted conscience; he is driven from one refuge to another, goes from mountain to hill, seeking rest and finding none; and therefore will the sooner prove that there is no rest to be found, nor trust to be put, in any creature whatsoever.

"It is therefore quite a wrong notion that some entertain, that the more they do, the more they shall depend on it. Whereas the reverse is true; the more they do, or the more thorough they are in seeking, the less will they be likely to rest in their doings, and the sooner will they see the vanity of all that they do.
