With a close reading of both Hildegard and Bonhoeffer, Jennifer Campbell encourages the contemporary church to read the signs of the times and to reach out to those in need in prophetic witness to both the Word of God and the Holy Spirit. With a view to recovering a balanced and rounded theology of prophecy for the church today, she discusses the workings of both the Word of God (viewed as Christ and the Scriptures) and the Holy Spirit in the works and lives of two powerful prophetic leaders.
