117. Light is cast here upon the bondage to Satan by which our nature, entangled in sins, is oppressed. Hence Paul's expression, "children of wrath," Eph 2, 3, and the declaration that such are taken captive by Satan unto his will, 2 Tim 2, 26. For when we are mere men; that is, when we apprehend not the blessed seed by faith, we are all like Cain, and nothing is wanting but an opportunity. For nature, destitute of the Holy Spirit, is impelled by that same evil spirit which impelled wicked Cain. If, however, there were in any one those ample powers, or that free will, by which a man might defend himself against the assaults of Satan, these gifts would most assuredly have existed in Cain, to whom belonged the birthright and the promise of the blessed seed. But in that very same condition are all men! Unless nature be helped by the Spirit of God, it cannot maintain itself. Why, then, do we absurdly boast of free-will? Now follows another remarkable passage. B. How Cain Had to Give an Account, and His Conduct. V. 9. _And Jehovah said unto Cain, Where is Abel thy brother? And he said, I know not: Am I my brother's keeper?_ 118. Good God! into what depth of sin does our miserable nature fall when driven onward by the devil. Murder had been committed on a brother, and perhaps murdered Abel lay for days unburied. Thereupon, as Cain returned to his parents at the accustomed time, and Abel returned not with him, the anxious parents asked him: Cain, thou art here, but where is Abel? Thou hast returned home, but Abel has not returned. The flock is without their shepherd. Tell us therefore, where thy brother is. Upon this, Cain, becoming abusive, makes answer to his parents, by no means with due reverence, "I know not: Am I my brother's keeper?" 119. But it happened to Cain as to all the wicked, that by excusing himself he accused himself, according to the words of Christ, "Out of thine own mouth will I judge thee, thou wicked servant," Luke 19, 22. Also the heathen had a striking proverb among them, "A liar ought to have a good memory." Such was the judgment of heathen men, though they knew nothing of the judgment of God and of conscience, and had nothing to guide their judgment but their experience in civil affairs. And true it is that liars run much risk of being discovered and unmasked. Hence the Germans have the proverb, "A lie is a very fruitful thing." For one lie begets seven other lies, which become necessary to uphold the first lie. And yet it is impossible, after all, to prevent conscience from arousing and betraying itself at times, if not in words, then in gestures. This is proved by numberless examples. I will cite only one example here:
