Passage
Then said Jesus unto them, When ye have lifted up the Son of man, then shall ye know that I am he, and that I do nothing of myself; but as my Father hath taught me, I speak these things.
Then said Jesus unto them, When ye have lifted up the Son of man, then shall ye know that I am he, and that I do nothing of myself; but as my Father hath taught me, I speak these things.
John 8:26 I have many things to say and to judge of you: but he that sent me is true; and I speak to the world those things which I have heard of him.
John 8:27 They understood not that he spake to them of the Father.
John 8:28 Then said Jesus unto them, When ye have lifted up the Son of man, then shall ye know that I am he, and that I do nothing of myself; but as my Father hath taught me, I speak these things.
John 8:29 And he that sent me is with me: the Father hath not left me alone; for I do always those things that please him.
John 8:30 As he spake these words, many believed on him.
The verse centers on "said", "jesus", "lifted", "shall", "nothing", "myself", "father", and "hath". It is saying that the verse draws attention to "said" and "jesus", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 27's "They understood not that he spake to..." into verse 29's "And he that sent me is with...", so "said" and "jesus" 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 "said" and "jesus" with trust shaped by these words, not by a vague optimism outside the passage.
