Passage
These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.
These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.
John 16:31 Jesus answered them, Do ye now believe?
John 16:32 Behold, the hour cometh, yea, is now come, that ye shall be scattered, every man to his own, and shall leave me alone: and yet I am not alone, because the Father is with me.
John 16:33 These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.
The verse centers on "world", "things", "spoken", "might", "peace", "shall", "tribulation", and "good". It is saying that the verse draws attention to "world" and "things", so its meaning should be read from those terms before moving to application.
The prior verse says "Behold the hour cometh yea is now...", giving immediate footing for "world" and "things". 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 "world" and "things" with trust shaped by these words, not by a vague optimism outside the passage.
