John 17:17 (KJV)
Sanctify them through thy truth: thy word is truth.
Jesus prayed for the disciples to be sanctified. This sanctification would come from the living word. The word that John spoke of in the beginning of the gospel, Jesus himself is the living word.
Jesus had just proclaimed in John 14: 6 I am the way, the truth, and the life: no man cometh unto the Father, but by me. This is one of the most powerful statements in all of scripture. Jesus says once again that he is the only way to God. by believing this the disciples would be sanctified.
The word is still alive today. The living word sits at the right hand of father and whoever believes in that the word is truth will be sanctified. This sanctification comes when each Christians accepts Jesus as their personal Lord and savior.
Each of us who have accepted your son as our lord and savior are truly sanctified, reborn into the kingdom of God. Give us the wisdom to understand the responsibility that goes with being one of your saints. The courage to be able to walk this world with our heads held high proclaiming the truths of the living word.
In Jesus name we pray amen.
