1 Thessalonians 5:23
And the very God of peace, sanctify you wholly, and I pray God that your whole spirit, soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
God never has and never will do anything apart from His Word. That's an eternal, everlasting fact. It cannot be changed. Yet, we act as though that isn't true when we try everything we can think of to get a hold of God. We cry, we pray, we fast, we do all sorts of things. But we don't stop and realize that the Word, the written Word of God, is just as much God as the Father, Son and Holy Ghost, are God.
The Apostle John writes, "In the beginning was the Word, and the Word was with God, and the Word was God. All things were made by him" (John 1:1, 3)
We can agree that all things were made by God. What we fail to see however, is that John was saying, "All things were made by God, and all things were made by the Word." You see, the book we call "The Holy Bible" is not just a book about somebody. It is Somebody. It is God, Himself, manifested to us.
Moments before Jesus went to the cross, He prayed for His disciples: "Sanctify them through thy truth: thy word is truth. And for their sakes I sanctify myself, that they also might be sanctified through the truth [the Word]" (John 17:17, 19).
This prayer wasn't just for the disciples because Jesus went on to pray, "Neither pray I for these alone, but for them also [this is us] which shall believe on me through their word" (verse 20).
Like the disciples, we are sanctified through the truth, through God's Word. But notice, so was Jesus. He said, "I sanctify myself " How did Jesus sanctify Himself? It was through the truth, it was through the Word. We are sanctified the same way that Jesus was sanctified, by the truth, by the Word of God.
