As Jesus faces his death, he is concerned about the future of his disciples. Now that the disciples have "believed that you sent me", Jesus knows that the world will reject them as the authorities have already said that anyone who accepts Jesus will be put out of the synagogues. This prayer is a prayer of protection made possible by the indwelling of the Holy Spirit. It is the power of the Holy Spirit that will allow the disciples not only to be in the world protected but will empower them to go into all the world with the truth in their hearts. Jesus is the word and Jesus is the truth. "Your word is truth" and that truth is the indwelling of Jesus. This is sanctification. Not separation from the world but a dedication of our heart and soul to God. As the will of God manifests in our lives, the truth of Jesus is revealed through us and into the world. That truth will be rejected but the Father will keep us from corruption.
John 17:17 Sanctify them in the truth; your word is truth.
What is the truth? How do determine the truth?
What authority do rely on? Radio, news, online? Which one?
Where does God fit in?
If prayer and your source of authority conflict, who do you choose?
Do you shape the word to fit you or does the word shape you?
