Passage
He was in the world, and the world was made by him, and the world knew him not.
He was in the world, and the world was made by him, and the world knew him not.
John 1:8 He was not that Light, but was sent to bear witness of that Light.
John 1:9 That was the true Light, which lighteth every man that cometh into the world.
John 1:10 He was in the world, and the world was made by him, and the world knew him not.
John 1:11 He came unto his own, and his own received him not.
John 1:12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
The verse centers on "world" and "knew". It is saying that the verse draws attention to "world" and "knew", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "That was the true Light which lighteth..." into verse 11's "He came unto his own and his...", so "world" and "knew" 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 "knew" with trust shaped by these words, not by a vague optimism outside the passage.
