A.W. Tozer, a popular evangelical author and Christian mystic, wrote The Knowledge of the Holy. Tozer exposes God's characteristics, from wisdom to grace to mercy, in an endeavour to restore the majesty and amazement of God in all Christians' hearts and thoughts. The Knowledge of the Holy is a modern classic of Christian testimony and devotion that shows us how to revitalise our prayer habits, ponder more reverently, understand God more completely, and feel God's presence in our everyday lives.
