Passage
She saith to him: Yea, Lord, I have believed that thou art Christ, the Son of the living God, who art come into this world.
She saith to him: Yea, Lord, I have believed that thou art Christ, the Son of the living God, who art come into this world.
John 11:25 Jesus said to her: I am the resurrection and the life: he that believeth in me, although he be dead, shall live:
John 11:26 And every one that liveth and believeth in me shall not die for ever. Believest thou this?
John 11:27 She saith to him: Yea, Lord, I have believed that thou art Christ, the Son of the living God, who art come into this world.
John 11:28 And when she had said these things, she went and called her sister Mary secretly, saying: The master is come and calleth for thee.
John 11:29 She, as soon as she heard this, riseth quickly and cometh to him.
The verse centers on "world", "saith", "lord", "believed", "thou", "christ", "living", and "come". It is saying that the verse draws attention to "world" and "saith", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 26's "And every one that liveth and believeth..." into verse 28's "And when she had said these things...", so "world" and "saith" 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 "world" and "saith" with trust shaped by these words, not by a vague optimism outside the passage.
