Passage
And early in the morning he came again into the temple, and all the people came to him; and he sat down and taught them.
And early in the morning he came again into the temple, and all the people came to him; and he sat down and taught them.
John 8:1 But Jesus went to the mount of Olives.
John 8:2 And early in the morning he came again into the temple, and all the people came to him; and he sat down and taught them.
John 8:3 And the scribes and the Pharisees bring [to him] a woman taken in adultery, and having set her in the midst,
John 8:4 they say to him, Teacher, this woman has been taken in the very act, committing adultery.
The verse centers on "early", "morning", "came", "again", "temple", "people", and "down". It is saying that the verse draws attention to "early" and "morning", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "But Jesus went to the mount of..." into verse 3's "And the scribes and the Pharisees bring...", so "early" and "morning" 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 "early" and "morning" with trust shaped by these words, not by a vague optimism outside the passage.
