Sanctify them through thy truth: thy word is truth—

 Our Lord always links the progress and development of our spiritual life with our receiving and obeying the Truth, and every child of God should beware of that teaching which claims to be in advance of the Word and that Christ or the holy Spirit speaks to such advanced Christians independently of the Word. It cultivates spiritual pride and boastfulness, and renders powerless the warnings and expostulations of the sacred Scriptures because the deluded ones think they have a higher teacher dwelling in them. And Satan, taking advantage of the delusion, leads them captive at his will.
