In this study Judith Krawelitzki shows that, within the Old Testament, clear and unambiguous speech about God's power finds its origin in the Book of Psalms, where three interrelated perspectives emerge: power as a quality of the divine essence, power as a gift God shares with human beings, and his actions and interactions in the world with humanity as proof of divine power. All three share the conviction that in its very essence, divine power is a saving power that manifests God's steadfast love for his people. This theology, developed in the Psalter through the language of prayer, shaped the discourse concerning God's power elsewhere in the Old Testament, while the concept of divine power continues to provide a compelling framework for understanding and elucidating the being and actions of God.
