"I have told you these things so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world." (John 16:33)
(Read John 15 and 16)
At the end of John 16, Jesus recaps all He has has said from the beginning of chapter 15 by giving the reason why He has told us "these things". He has told us so that in Him we might have peace. Peace is what Jesus has come to bring, and the peace He brings will come by way of a whole heap of worldly trouble. Still He says, "But take heart! I have overcome the world."
What things do you see in chapters 15 and 16 that bring peace simply because Jesus told them? What consistent theme or themes do you see running through chapters 13-16? What is Jesus' command, and how should we obey that command in this world full of trouble?
