There are more than veiled references to the Holy Spirit in the Old Testament. The Spirit is seen as the creator, the renewer of the life of humanity in redemption, as the Person through whom the prophets of the Lord were inspired and through whom men and women received the gifts of wisdom for leadership, administration, and craftsmanship. Dr. Wood concludes his study by showing that the concepts of regeneration, indwelling, sealing, filling, and empowering by the Spirit were already in action in the Old Testament. He presents a comparative study of the words for spirit in both testaments and shows how the Old Testament revelation serves as a background and a basis for a fuller understanding of the complete work of the spirit in present New Testament age of fulfillment.
