Passage
His disciples say to him, Lo, now thou speakest openly and utterest no allegory.
His disciples say to him, Lo, now thou speakest openly and utterest no allegory.
John 16:27 for the Father himself has affection for you, because ye have had affection for me, and have believed that I came out from God.
John 16:28 I came out from the Father and have come into the world; again, I leave the world and go to the Father.
John 16:29 His disciples say to him, Lo, now thou speakest openly and utterest no allegory.
John 16:30 Now we know that thou knowest all things, and hast not need that any one should demand of thee. By this we believe that thou art come from God.
John 16:31 Jesus answered them, Do ye now believe?
The verse centers on "disciples", "thou", "speakest", "openly", "utterest", and "allegory". It is saying that the verse draws attention to "disciples" and "thou", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 28's "I came out from the Father and..." into verse 30's "Now we know that thou knowest all...", so "disciples" and "thou" 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 "disciples" and "thou" with trust shaped by these words, not by a vague optimism outside the passage.
