Passage
And he that has sent me is with me; he has not left me alone, because I do always the things that are pleasing to him.
And he that has sent me is with me; he has not left me alone, because I do always the things that are pleasing to him.
John 8:27 They knew not that he spoke to them of the Father.
John 8:28 Jesus therefore said to them, When ye shall have lifted up the Son of man, then ye shall know that I am [he], and [that] I do nothing of myself, but as the Father has taught me I speak these things.
John 8:29 And he that has sent me is with me; he has not left me alone, because I do always the things that are pleasing to him.
John 8:30 As he spoke these things many believed on him.
John 8:31 Jesus therefore said to the Jews who believed him, If ye abide in my word, ye are truly my disciples;
The verse centers on "sent", "left", "alone", "always", "things", and "pleasing". It is saying that the verse draws attention to "sent" and "left", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 28's "Jesus therefore said to them When ye..." into verse 30's "As he spoke these things many believed...", so "sent" and "left" 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 "sent" and "left" with trust shaped by these words, not by a vague optimism outside the passage.
