Jesus answered them, “Truly, truly, I say to you, everyone who practices sin is a slave to sin.
34. Every man who committeth sin is the slave of sin. This is an argument drawn from contrary things. They boasted that they were free. He proves that they are the slaves of sin, because, being enslaved by the desires of the flesh, they continually sin. It is astonishing that men are not convinced by their own experience, so that, laying aside their pride, they may learn to be humble.
Christ turns from the hardened Pharisees to address those few weak believers with comfort, because He gathers lambs in His arms and will not cast off faith in its infancy. The rule He sets down is settled: He owns none for His true disciples but those who continue in His Word, though many profess themselves His disciples only in show and name.
