I received an email containing the quote from A. W. Tozer and thought it worth sharing:
Sound Bible exposition is an imperative must in the Church of the Living God. Without it no church can be a New Testament church in any strict meaning of that term. But exposition may be carried on in such way as to leave the hearers devoid of any true spiritual nourishment whatever. For it is not mere words that nourish the soul, but God Himself, and unless and until the hearers find God in personal experience they are not the better for having heard the truth. The Bible is not an end in itself, but a means to bring men to an intimate and satisfying knowledge of God, that they may enter into Him, that they may delight in His presence, may taste and know the inner sweetness of the very God Himself in the core and center of their hearts.
