Then the Jews said to him, “Now we know that you have a demon. Abraham died, and the prophets; and you say, ‘If a man keeps my word, he will never taste of death.’
John 8:50 But I don’t seek my own glory. There is one who seeks and judges.

John 8:52 Then the Jews said to him, “Now we know that you have a demon. Abraham died, and the prophets; and you say, ‘If a man keeps my word, he will never taste of death.’

John 8:54 Jesus answered, “If I glorify myself, my glory is nothing. It is my Father who glorifies me, of whom you say that he is our God.
The verse centers on "jews", "said", "demon", "abraham", "died", "prophets", "keeps", and "word". It is saying that the verse draws attention to "jews" and "said", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 51's "Most certainly I tell you if a..." into verse 53's "Are you greater than our father Abraham...", so "jews" and "said" 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 "jews" and "said" with trust shaped by these words, not by a vague optimism outside the passage.
