One definition of a Christian mystic is someone who engages in deep, prayerful pondering of the nature of God, as He is revealed in the Scriptures, and then emerges from those intimate encounters to share with us what he or she has learned. I would put A.W. Tozer in this category, especially in his book The Knowledge Of The Holy—The Attributes of God: Their Meaning in the Christian Life.
Tozer himself described the Christian mystic more fully than I could in his book The Christian Book Of Mystical Verse. In that book, Tozer shared some poetic verses from some of his favorite mystical thinkers. He noted, “The hymns and poems found here are mystical in that they are God-oriented; they begin with God, embrace the worshipping soul, and return to God again.”
In The Knowledge Of The Holy, Tozer takes us on his own personal journey into the immeasurable depths of God’s greatness. Whereas many theologians tend to focus on one attribute of God at a time, Tozer has a God-given ability to help us see all of God’s attributes operating in their infinite fullness.
Even as Tozer plunges deep into the attributes of God’s self-existence, self-sufficiency, omniscience, omnipotence, omnipresence, love, mercy, justice, grace, and sovereignty, he reminds us, “Because God is immutable He always acts like Himself, and because He is a unity He never suspends one of His attributes in order to exercise another.”
This is not a book you can ready lightly or casually, or even quickly. This is a book that invites you to read slowly and reverently each of the short chapters, and then to meditate long on the immenseness of an All-Powerful, All-Loving God who wants to reveal Himself to you.
The Knowledge Of The Holy is a soul-expanding book!
