Matthew Poole and continuators on John 8:34

34 Jesus answered them, Verily, verily I say unto you, Whosoever committeth sin, is the servant of sin .

Our Saviour here Correcteth their mistake, letting them know, That he was not speaking about any Corporal, but Spiritual Servitude; not of the freedom of Mens Bodies from the power of Enemies, but of the freedom of Mens Souls from the slavery and dominion of Lusts and Corruptions. He that doth sin (saith he) is the servant of sin. The committing or doing of Sin here intended, is not to be understood of single Acts of Sin, (for in that sense, who lives and sinneth not? (The righteous man sinning seven times in a day) so as all men would be concluded the Servants of Sin); but of living Indulgently and Habitually in a course of Sin, and in the practise of gross Sins: in which sense Workers of iniquity is to be taken, Matt. 7.23. And this very Phrase, 1 Iohn 3.4. And indeed, the very Heathen could see, that there was no such slavery as a Servitude to Lusts and Passions; Men are the Servants of Corruption, 2 Pet. 2.19. under the Dominion of sin, Rom. 6.20.
