Passage
He came unto his own: and his own received him not.
He came unto his own: and his own received him not.
John 1:9 That was the true light, which enlighteneth every man that cometh into this 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, he gave them power to be made the sons of God, to them that believe in his name.
John 1:13 Who are born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
The verse centers on "came" and "received". It is saying that the verse draws attention to "came" and "received", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "He was in the world and the..." into verse 12's "But as many as received him he...", so "came" and "received" 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 "came" and "received" with trust shaped by these words, not by a vague optimism outside the passage.
