Read John 17:16-19

[Jesus prayed] “They do not belong to this world any more than I do. Make them holy by your truth; teach them your word, which is truth.” -John 17:16-17 (NLT)

Having been called by Jesus, we no longer belong to this world. As the truth of God’s Word changes us, we become more and more unlike this world, more and more ready for the next. And we cannot do this on our own; only the truth of God’s Word can work this change in us.
