(7.) The sin of the exterior parts, tongue, hand, eyes, feet, &c. is only in act, and not in habit, or at least, the habits are weak and subject to the will. And it is in the execution of the sinful desires of the flesh, and commands of the will, that the same consisteth. These parts also are not the primary subject of the guilt, but the will, that either positively puts them upon evil, or doth not restrain them when it ought; and so they are guilty but participatively and secondarily, as the other imperate faculties are: it is not good or evil merely as it is the act of tongue or hand, but as it is the act of the tongue, or hand of a rational free agent (agreeable or disagreeable to the law). If a madman should speak blasphemy, or should kill, or steal, it were no further sin, than as he had voluntarily contracted the ill disposition which caused it while he had the use of reason. If a man's hand were held and forced by another to do mischief utterly against his will, it is the sin of the chief agent, and not of the involuntary instrument. But no force totally excuseth us from guilt, which leaveth the act to our rational choice. He that saith, Take this oath, or I will kill thee, or torment thee, doth use force as a temptation which may be resisted, but doth not constrain a man to swear: for he leaveth it to his choice whether he will swear, or die, or be tormented; and he may and ought to choose death rather than the smallest sin. The will may be tempted, but not constrained. _Direct._ II. 2. Labour clearly to understand the evil of sin, both intrinsical in itself, and in its aggravations and effects.--When you have found out where it is, and wherein it doth consist, find out the malignity and odiousness of it. I have heard some christians complain, that they read much to show them the evil of sin in its effects, but meet with few that show them its evil in itself sufficiently. But, if you see not the evil of sin in itself, as well as in the effects, it will but tempt you to think God unjust in over-punishing it; and it will keep you from the principal part of true repentance and mortification; which lieth in hating sin, as sin. I shall therefore show you, wherein the intrinsical malignity of sin consisteth. 1. Sin is (formally) the violation of the perfect, holy, righteous law of God. 2. It is a denial or contempt of the authority, or governing power, of God: as if we said, Thou shalt not be our Governor in this. 3. It is a usurping the sovereign power to ourselves of governing ourselves, in that act: for when we refuse God's government, we set up ourselves in his stead; and so make gods of ourselves as to ourselves, as if we were self-sufficient, independent, and had right hereto. 4. It is a denying or contempt of the wisdom of God, as if he had unwisely made us a law which is unmeet to rule us.
