Passage
And the bondservant abideth not in the house for ever: the son abideth for ever.
And the bondservant abideth not in the house for ever: the son abideth for ever.
John 8:33 They answered unto him, We are Abraham`s seed, and have never yet been in bondage to any man: how sayest thou, Ye shall be made free?
John 8:34 Jesus answered them, Verily, verily, I say unto you, Every one that committeth sin is the bondservant of sin.
John 8:35 And the bondservant abideth not in the house for ever: the son abideth for ever.
John 8:36 If therefore the Son shall make you free, ye shall be free indeed.
John 8:37 I know that ye are Abraham`s seed: yet ye seek to kill me, because my word hath not free course in you.
The verse centers on "bondservant", "abideth", "house", and "ever". It is saying that the verse draws attention to "bondservant" and "abideth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 34's "Jesus answered them Verily verily I say..." into verse 36's "If therefore the Son shall make you...", so "bondservant" and "abideth" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "bondservant" and "abideth" with trust shaped by these words, not by a vague optimism outside the passage.
