John 8:34

And why did not Christ confute them, for they had often been in bondage to the Egyptians, Babylonians, and many others? Because His words were not to gain honor for Himself, but for their salvation, for their benefit, and toward this object He was pressing. For He might have spoken of the four hundred years, He might have spoken of the seventy, He might have spoken of the years of bondage during the time of the Judges, at one time twenty, at another two, at another seven; He might have said that they had never ceased being in bondage. But He desired not to show that they were slaves of men, but that they were slaves of sin, which is the most grievous slavery, from which God alone can deliver; for to forgive sins belongeth to none other.

"Whosoever committeth sin is the servant of sin." Showing that this is the freedom of which He speaketh, the freedom from this service.

(Tr. xli. 3) This asseveration is important: it is, if one may say so, His oath. Amen means true, but is not translated. Neither the Greek nor the Latin Translator have dared to translate it. It is a Hebrew word; and men have abstained from translating it, in order to throw a reverential veil over so mysterious a word: not that they wished to lock it up, but only to prevent it from becoming despised by being exposed. How important the word is, you may see from its being repeated. Verily I say unto you, says Verity itself; which could not be, even though it said not verily. Our Lord however has recourse to this mode of enforcing His words, in order to rouse men from their state of sleep and indifference. Whosoever, He saith, committeth sin, whether Jew or Greek, rich or poor, king or beggar, is the servant of sin. O miserable bondage! The slave of a human master when wearied with the hardness of his tasks, sometimes takes refuge in flight. But whither does the slave of sin flee? He takes it along with him, wherever he goes; for his sin is within him. The pleasure passes away, but the sin does not pass away: its delight goes, its sting remains behind.

"Verily, verily, I say unto you, that every one who committeth sin is the servant of sin." Miserable slavery! Men frequently, when they suffer under wicked masters, demand to get themselves sold, not seeking to be without a master, but at all events to change him. What can the servant of sin do? To whom can he make his demand? To whom apply for redress? Of whom require himself to be sold? And then at times a man's slave, worn out by the commands of an unfeeling master, finds rest in flight. Whither can the servant of sin flee? Himself he carries with him wherever he flees. An evil conscience flees not from itself; it has no place to go to; it follows itself. Yea, he cannot withdraw from himself, for the sin he commits is within.

(iv. Mor. c. 42. in Nov. Ex. 21) Because whoever yields to wrong desires, puts his hitherto free soul under the yoke of the evil one, and takes him for his master. But we oppose this master, when we straggle against the wickedness which has laid hold upon us, when we strongly resist habit, when we pierce sin with repentance, and wash away the spots of filth with tears. (xxv. Moral. c. 20. not in Nov. Ex. 14) And the more freely men follow their perverse desires, the more closely are they in bondage to them.
