And now to shew that the heart has given in a false report of the temptation, we may learn from this, that the same weak man would resist and master the same powerful temptation, upon considerations of infinitely less value than those which religion offers, nay such vile considerations, that the grace of God cannot without blasphemy be supposed to add any manner of force and efficacy to them. Thus for instance, it would be a hard matter to dress up a sin in such soft and tempting circumstances, that a truly covetous man would not resist for a considerable sum of money; when neither the hopes of heaven nor the fears of hell could make an impression upon him before. But can anything be a surer indication of the deceitfulness of the heart, than thus to shew more courage, resolution, and activity, in an ill cause, than it does in a good one? And to exert itself to better purpose, when it is to serve its own pride, or lust, or revenge, or any other passion, than when it is to serve God upon motives of the Gospel, and upon all the arguments that have ever been made use of to bring men over to religion and a good life? And thus having shewn that man is wonderfully apt to deceive and impose upon himself, in passing through the several stages of that great duty, repentance, I proceed now, in the _Second place_: To inquire into the grounds and reasons of this ignorance, _and to shew whence it comes to pass that man, the only creature in the world that can reflect and look into himself, should know so little of what passes within him, and be so very much unacquainted even with the standing dispositions and complexion of his own heart_. The prime reason of it is, because we so very seldom converse with ourselves, and take so little notice of what passes within us: For a man can no more know his own heart than he can know his own face, any other way than by reflection: He may as well tell over every feature of the smaller portions of his face without the help of a looking-glass, as he can tell all the inward bents and tendencies of his soul, those standing features and lineaments of the inward man, and know all the various changes that this is liable to from custom, from passion, and from opinion, without a very frequent use of looking within himself.
