_Ans._ 1. Corruption cannot stir in us, but therein we sin, for the very first rise, the _motus primo-primi_, as they are called, are sinful, being contrary to the holy law of God; and the very in-being of that old man is our sin; for it is sinful, and rebellious against God, yea it is very enmity and rebellion itself. When Satan cometh with a temptation from without, he findeth always much in us to entertain the temptation. So that the very stirring of corruption, which is occasioned by the temptation from without, is our guilt. 2. It is true it is our duty, to set against the first risings and motions of corruption, when it first enticeth, before it hath conceived or brought forth sin; and it will argue grace in life and in action, to be able to hinder the motions of lust so far, that it shall not conceive and bring forth sin. Yet we may not say, that there is no grace in the soul, or no measure of mortification attained, where lust sometimes not only enticeth, but conceiveth and bringeth forth sin. The sad experience of many of God's worthies, registrated in the word, cleareth this abundantly. We must not say, such an one is fallen, therefore he is dead. Paul reasoneth otherways, Rom. vii. 3. Yet even then, when lust conceiveth and bringeth forth sin, this may comfort and bear up the heart of a poor believer. (1.) That though corruption prevail so far, as to bear down all opposition, and run down all that standeth in its way, yet it getteth not the full consent of the soul: there is still a party for God in the soul, that opposeth so far as to protest against it, or at least to dissent from it, and not to will that which yet is done, and positively to will that which cannot be gotten effectuated, (2.) And further, this may bear up the poor soul, that there is a party within, which, though for a time, during the violent overrunning of corruption, can do little more than sigh and groan in a corner, yet is waiting and longing for an opportunity when it may appear more for God, and against that wicked usurper. (3.)So also this may comfort the poor soul, that as it perceiveth corruption stirring, and the old man moving one member or other, it runneth away to the king; and when it is not able to apprehend the traitor, and take him captive to the court of justice, doth there discover the traitor, and tell the king that there is such or such a traitor acting such and such rebellion against him and his laws, and complain and seek help to take the rebel prisoner, and bring him bound hand and foot to the king, that he may give out sentence against him; that is, when he can do no more against that raging enemy, maketh his complaint to the Lord, and lieth before him, sighing and groaning for help and strength to withstand and oppose more this enemy.
