Passage
And the dedication in Jerusalem came, and it was winter,
And the dedication in Jerusalem came, and it was winter,
John 10:20 and many of them said, `He hath a demon, and is mad, why do ye hear him?'
John 10:21 others said, `These sayings are not those of a demoniac; is a demon able blind men's eyes to open?'
John 10:22 And the dedication in Jerusalem came, and it was winter,
John 10:23 and Jesus was walking in the temple, in the porch of Solomon,
John 10:24 the Jews, therefore, came round about him, and said to him, `Till when our soul dost thou hold in suspense? if thou art the Christ, tell us freely.'
The verse centers on "dedication", "jerusalem", "came", and "winter". It is saying that the verse draws attention to "dedication" and "jerusalem", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 21's "others said These sayings are not those..." into verse 23's "and Jesus was walking in the temple...", so "dedication" and "jerusalem" 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 "dedication" and "jerusalem" with trust shaped by these words, not by a vague optimism outside the passage.
