Jesus did a whole lot of teaching in John 14, 15, and 16. He said a lot of deep things and clear instructions.
And then he prayed for them… John 17.
But before he prayed, he said this to them, “ I have told you these things, so that in Me you may have [perfect] peace and confidence. In the world you have tribulation and trials and distress and frustration; but be of good cheer [take courage; be confident, certain, undaunted]! For I have overcome the world. [I have deprived it of power to harm you and have conquered it for you.]
I love that. Whatever we have to face, Jesus has conquered it for you. For all our sisters and brothers facing terrible persecution in the world, the world won’t win. You can have perfect peace because Jesus is still on his throne. There is a home in Heaven for you because Jesus has conquered the world. You can have perfect peace, because you know where your real home is…..and Jesus has a place fixed up just for you.
And then he prayed for them……..
