This book introduces the reader to the discipline of biblical theology. In part one Helyer discusses the central problem of the unity of the Bible and the various options that have been proposed. He then argues for a vital connection between the testaments forming one grand story of redemptive history and one central theme, the coming kingdom of God. Part two takes up the theology of three major witnesses: Jesus, Paul, and John. In these three witnesses Helyer finds the center of New Testament thought. He emphasizes the importance of Jesus' teaching as foundational for all the other the New Testament witnesses. Without overlooking the diversity and individuality of the major witnesses, he clearly demonstrates the theological unity that binds them together and provides the key to the enduring message of Scripture.
