In The Beauty of Spiritual Language, Dr. Hayford describes his own experience and explains how he came to validate that experience. In sensible, biblical terms, he describes how tongues speaking is neither gibberish nor emotional exuberance, but rather an intimate encounter with the heart of God.
In a broad appeal that crosses denominational lines, Hayford makes a persuasive case for accepting tongues as a normal part of a Christian's experience. Anyone wanting an objective inquiry into the nature and biblical basis for this gift will appreciate The Beauty of Spiritual Language.
