14I have given them your word, and the world has hated them because they are not of the world, just as I am not of the world. 15I do not ask that you take them out of the world, but that you keep them from the evil one. 16They are not of the world, just as I am not of the world. 17Sanctify them in the truth; your word is truth. —john 17:14-17
I would suggest to you that John 17:17 is a great verse to put to memory. It has three little parts to it. Jesus prayed, Sanctify them. The word sanctify means change. Sanctification is God's transforming process in the life of every believer. Jesus prayed, "Change them, Father, all My disciples."
The second phrase is, in the truth. Do you want to change and grow? The fuel for transformation has always been and always will be truth. Sanctify them in the truth.
Where is truth found? Jesus didn't leave any doubt about that. The last phrase in verse 17 was, your word is truth. This is the Son praying to the Father. Every word that proceeds from the mouth of God is absolute, authoritative, binding truth.
The world can shout that it has discovered other truth, but what God says is still true! Within the last few years psychology has promoted the concept that if you really want to get healthy, if you want to get healed from the past, you have to dig it up. Joseph in the Old Testament and the Apostle Paul in the New Testament make God's heart abundantly clear: freedom from my past comes not from remembering and reviewing, but from forgetting and putting behind me and forgiving and moving on. This is the living, abiding, Word of God - always true, always reliable:
This is the greatest book that has ever been written because it is the only book that God has written. He has preserved, protected, and promoted it. It has the endorsements of the greatest minds of human history. This book has never been tried and found lacking. Never! Don't ever let someone make you back down from trusting God's Word. The Bible has never been really tried and found lacking, but it has been found very convicting and therefore not tried. —James MacDonald
