John 8:35

35 The slave does not have a permanent place in the household; the son has a place there forever.

John 8:35 In-Context

33 They answered him, "We are descendants of Abraham and have never been slaves to anyone. What do you mean by saying, "You will be made free'?"
34 Jesus answered them, "Very truly, I tell you, everyone who commits sin is a slave to sin.
35 The slave does not have a permanent place in the household; the son has a place there forever.
36 So if the Son makes you free, you will be free indeed.
37 I know that you are descendants of Abraham; yet you look for an opportunity to kill me, because there is no place in you for my word.
