It all ties together

The theological question of Jesus Christ necessarily leads to the question of the nature and development of God in the Old Testament; to reflection over God’s role as creator and as director of history by accompanying, freeing, teaching, and sanctifying his people; as well as to the interpretation of metaphors for God’s wisdom, kingship, and role as shepherd and father, which also took on significance in the New Testament. Christology thus requires a presentation of the basic theologies in the Old Testament and of a theology of the Old Testament. The history of Yahweh that emerges in the Old Testament and the theologies of creation, history, law, the cult, and wisdom collected therein—which, from the perspective of the New Testament, find their goal (τέλος [telos]) in the spatial-temporal focus and embodiment of God’s actions through Jesus Christ—thus contribute to the history of God in the New Testament, to the discourse on Jesus Christ, and to a biblical theology.—The Development of God in the Old Testament, page 101
