John 8:32-35

32And you will know the truth [regarding salvation], and the truth will set you free [from the penalty of sin].”

33They answered Him, “We are Abraham’s descendants and have never been enslaved to anyone. What do You mean by saying, ‘You will be set free’?”

34Jesus answered, “I assure you and most solemnly say to you, everyone who practices sin habitually is a slave of sin.

35Now the slave does not remain in a household forever; the son [of the master] does remain forever.
