A. W. TOZER began his lifelong pursuit of God at the age of seventeen after hearing a street preacher. He never attended high school or seminary--his spiritual understanding came from the power of the Word and the power of the Spirit. While serving as a pastor and magazine editor, he wrote prolifically about basic spiritual disciplines and their relationship to contemporary life. His powerful use of words continues to grip the intellect and stir the soul of today's reader.
