This distinguished New Testament scholar calls his book by this title because he has a deep conviction that men cannot effectively spread a faith until they know what it really is; that Evangelism must always depend upon a knowledge of Doctrine. Nor is doctrine anything other than plain, clear teaching; yet thousands of sincere Christians have little idea that the Faith they cherish does comprise such marvels in its Creed. In this book Dr. Taylor examines the Christian doctrines one by one in a simple yet deeply moving and revealing way, and throws light upon all that he touches.
