Passage
But that the word may be fulfilled which is written in their law: they hated me without cause.
But that the word may be fulfilled which is written in their law: they hated me without cause.
John 15:23 He that hateth me hateth my Father also.
John 15:24 If I had not done among them the works that no other man hath done, they would not have sin: but now they have both seen and hated both me and my Father.
John 15:25 But that the word may be fulfilled which is written in their law: they hated me without cause.
John 15:26 But when the Paraclete cometh, whom I will send you from the Father, the Spirit of truth, who proceedeth from the Father, he shall give testimony of me.
John 15:27 And you shall give testimony, because you are with me from the beginning.
The verse centers on "word", "fulfilled", "written", "hated", "without", and "cause". It is saying that the verse draws attention to "word" and "fulfilled", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 24's "If I had not done among them..." into verse 26's "But when the Paraclete cometh whom I...", so "word" and "fulfilled" 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 "word" and "fulfilled" with trust shaped by these words, not by a vague optimism outside the passage.
