Expositor's Bible Commentary Commentary John 8:34

"Jesus answered them, Verily, verily, I say unto you, Every one that committeth sin is the bondservant of sin." — John 8:34 (ASV)

Jesus’ reply dealt with the spiritual aspect of freedom. Sin enslaves because every act of disobedience to God creates an atmosphere of alienation and a trend to further disobedience that inevitably makes escape impossible. An act of sin can possibly be overcome, but the attitude and habit of sin are inescapable.
