Yet He does not dismiss him without counsel, holy, just, and good. "Fret not thyself," He says, "for unto thee shall be his turning, and thou shalt rule over him." Over his brother, does He mean? Most certainly not. Over what, then, but sin? For He had said, "Thou hast sinned," and then He added, "Fret not thyself, for to thee shall be its turning, and thou shalt rule over it."[151] And the "turning" of sin to the man can be understood of his conviction that the guilt of sin can be laid at no other man's door but his own. For this is the health-giving medicine of penitence, and the fit plea for pardon; so that, when it is said, "To thee its turning," we must not supply "shall be," but we must read, "To thee let its turning be," understanding it as a command, not as a prediction. For then shall a man rule over his sin when he does not prefer it to himself and defend it, but subjects it by repentance; otherwise he that becomes protector of it shall surely become its prisoner. But if we understand this sin to be that carnal concupiscence of which the apostle says, "The flesh lusteth against the spirit,"[152] among the fruits of which lust he names envy, by which assuredly Cain was stung and excited to destroy his brother, then we may properly supply the words "shall be," and read, "To thee shall be its turning, and thou shalt rule over it." For when the carnal part which the apostle calls sin, in that place where he says, "It is not I who do it, but sin that dwelleth in me,"[153] that part which the philosophers also call vicious, and which ought not to lead the mind, but which the mind ought to rule and restrain by reason from illicit motions,--when, then, this part has been moved to perpetrate any wickedness, if it be curbed and if it obey the word of the apostle, "Yield not your members instruments of unrighteousness unto sin,"[154] it is turned towards the mind and subdued and conquered by it, so that reason rules over it as a subject. It was this which God enjoined on him who was kindled with the fire of envy against his brother, so that he sought to put out of the way him whom he should have set as an example. "Fret not thyself," or compose thyself, He says: withhold thy hand from crime; let not sin reign in your mortal body to fulfil it in the lusts thereof, nor yield your members instruments of unrighteousness unto sin. "For to thee shall be its turning," so long as you do not encourage it by giving it the rein, but bridle it by quenching its fire. "And thou shalt rule over it;" for when it is not allowed any external actings, it yields itself to the rule of the governing mind and righteous will, and ceases from even internal motions. There is something similar said in the same divine book of the woman, when God questioned and judged them after their sin, and pronounced sentence on them all,--the devil in the form of the serpent, the woman and her husband in their own persons.
