12. As we cannot expect a full conquest of the body of death, so long as we are here, as was shown above, neither can we expect a full and final victory over any one lust, which ever we have been troubled with. It is true, believers may be kept from some gross out-breaking of a corruption, which sometime prevailed, as Peter was from relapsing into an open and downright denying his Master; yet that same corruption did afterward stir, though not so violently as to carry him to such an height of sin; yet so far as to cause him do that which was a partial denying of his Master, when Paul withstood him to the face, because he was to be blamed for withdrawing from the Gentiles, for fear of them of the circumcision, &c. Gal. ii. 11, 12.: So, though a particular lust may be so far subdued through grace, as that for some considerable time a man may not find it so violent as it was; yet be cannot say that it is totally killed, because it may stir thereafter in some weaker measure; yea, he cannot tell, but ere he come to die, that same corruption may rise to be as violent as ever, and that Satan may again think to enter the soul at that same breach which once he entered at; yea, and who can tell, whether God may not suffer that corruption, which lay long as dead, to revive again for a time, and for a time drive the soul as violently as ever, and prevail for a time? And this should teach all to walk soberly, watchfully, and in fear, and to have a vigilant eye, even upon such lusts and carnal affections, as they may suppose they have got the victory of. 13. We would not think that we gain no ground upon corruption, because we still perceive it stirring, less or more; for as corruption is not always strongest, as was said above, nor hath the deepest footing in the soul, when its motions and stirrings are most felt; so neither must we think that there is no ground gained upon a lust, because we are still troubled and molested with its stirrings; for it is a great advantage to be more sensible of the motions of this enemy; and our more faithful and active wrestling against it may make its least stirrings more sensible to us; as the motions and trouble which a malefactor, while in grips and in prison, maketh, may be thought more of than his greater ragings before he was apprehended; yet he may be sure in fetters for all that. A beast that hath gotten death's blow may get out of grips, and run more mad than ever, and yet will die at length of the same blow.
