Passage
He therefore, having received the morsel, went out immediately. And it was night.
He therefore, having received the morsel, went out immediately. And it was night.
John 13:28 Now no man at the table knew to what purpose he said this unto him.
John 13:29 For some thought, because Judas had the purse, that Jesus had said to him: Buy those things which we have need of for the festival day: or that he should give something to the poor.
John 13:30 He therefore, having received the morsel, went out immediately. And it was night.
John 13:31 When he therefore was gone out, Jesus said: Now is the Son of man glorified; and God is glorified in him.
John 13:32 If God be glorified in him, God also will glorify him in himself: and immediately will he glorify him.
The verse centers on "therefore", "having", "received", "morsel", "went", "immediately", and "night". It is saying that the verse draws attention to "therefore" and "having", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 29's "For some thought because Judas had the..." into verse 31's "When he therefore was gone out Jesus...", so "therefore" and "having" 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 "therefore" and "having" with trust shaped by these words, not by a vague optimism outside the passage.
