What are some of the positive major insights or conclusions of this study? We may list the following:
(1) without a deep concern for careful contextual interpretation and the historical givenness of the text, much can go wrong when one attempts to do biblical theology. In particular, the OT must be allowed to have its own say, its own contribution to biblical theology, which is chiefly to provide us with a portrait of Yahweh, the creator God, and how he called and formed a people which came to be called Israel.
(2) Biblical theology also requires a commitment to a theology of progressive revelation. Really, protoTrinitarian and then Trinitarian thinking does not begin before the Christ event, and then only gradually does it become clear that even Binitarian thinking (a Godhead involving the Father and the Son) will not be adequate. The NT canon is progressively more Trinitarian the further one goes in the canon. This is not simply an evolutionary or chronological development, because some of the highest Christology is some of the earliest – for instance in Paul’s letters and perhaps in Hebrews as well.
(3) While covenantal theology is a very important part of biblical theology, it is critical to realize that with the exception of the New Covenant, none of those covenants were everlasting or permanent covenants, and it is incorrect to say that there has just been one covenant between God and his people, in many administrations. Furthermore, there are no unilateral or unconditional covenants in the Bible, either. Furthermore, HESED means mercy, not God’s tenacious loyalty to a particular covenant, say the Mosaic covenant. God is faithful to his character, and to his promises based on his character, but covenants come and go, are fulfilled or become obsolete until the new Christ-inaugurated and Christ-centered covenant appears.
(4) God’s grace, like God’s love, is not given with no thought of return. On the contrary it is intended to start an ongoing relationship and the recipient is expected to love God with his or her whole heart. Nor is grace, even in the NT, “perfected” in such a way that it becomes totally ‘perfected” in such a way that it becomes totally irresistible, such that we can deny there actually are apostasy texts in the Bible. This is not even true of Pauline or Johannine theology, never mind biblical theology.
(5) Election and salvation, though interrelated matters, are not identical matters. For example, Christ is God’s chosen one, his anointed Elect One, but he does not need to be saved. Furthermore, in both the OT and the NT one can be among or a part of the elect people, and in the end not be saved. Furthermore, as we noted repeatedly, salvation in the OT does not refer to “salvation by grace through faith in Jesus Christ.” Indeed, it often refers simply to God rescuing, redeeming from bondage, or healing some OT figure or group. One has to have an understanding of how the concept of salvation grew and developed as time went on and the canon grew larger.
(6) While covenantal nomism is an adequate way to speak about the Mosaic covenant, which was indeed inaugurated and sustained by God s grace, the New Covenant does not lack commandments or law, called the Law of Christ, so the old Protestant contrast between a law covenant and a grace covenant, or worse a God of law and judgment in the OT pitted over against a God of grace and redemption in the New Covenant, does no justice to either the OT or the NT, to either the Mosaic or the New Covenant.
(7) Finally, we used the word “convergence” in the subtitle precisely because all the pieces of a necessary full-fledged biblical theology do not emerge until all the lines of development about the Father, Son, and Spirit and redemption converge in the NT, and in particular from about the Gospel of John on in the NT, reading progressively through the canonical witness rather than just chronologically.
