John 17:14 Meaning

12While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.

13And now come I to thee; and these things I speak in the world, that they might have my joy fulfilled in themselves.

14I have given them thy word; and the world hath hated them, because they are not of the world, even as I am not of the world.

15I pray not that thou shouldest take them out of the world, but that thou shouldest keep them from the evil.

16They are not of the world, even as I am not of the world.
