Passage
She saith unto him, Yea, Lord: I have believed that thou art the Christ, the Son of God, [even] he that cometh into the world.
She saith unto him, Yea, Lord: I have believed that thou art the Christ, the Son of God, [even] he that cometh into the world.
John 11:25 Jesus said unto her, I am the resurrection, and the life: he that believeth on me, though he die, yet shall he live;
John 11:26 and whosoever liveth and believeth on me shall never die. Believest thou this?
John 11:27 She saith unto him, Yea, Lord: I have believed that thou art the Christ, the Son of God, [even] he that cometh into the world.
John 11:28 And when she had said this, she went away, and called Mary her sister secretly, saying, The Teacher is her, and calleth thee.
John 11:29 And she, when she heard it, arose quickly, and went unto him.
The verse centers on "world", "saith", "lord", "believed", "thou", "christ", "even", and "cometh". 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 whosoever liveth and believeth on me..." into verse 28's "And when she had said this she...", 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.
