(John 17:17 KJV) Sanctify them through thy truth: thy word is truth.
Truth is God’s revelation of Himself and His way in His Word. God’s Word is truth. Truth is the means by which we are made holy, sanctified. It is by hearing God's Word, accepting God's Word and applying His Word to our life that we grow in holiness. Truth will always lead us to a holy life. Any teaching which tends to draw us away from a life of holiness is not truth. Let's allow God's Word to sanctify us, to make us more like Jesus in every way.
