The Old Testament was already understood by Jews — not just Christians — as pointing to a coming Messiah. The breadth and robustness of typological and prophetic connections to Jesus across the OT (seed of the woman, angel of the Lord, Melchizedek, prophet like Moses, bronze serpent, Joseph, High Priest, kinsman redeemer, Davidic King, last Adam) constitutes a meta-narrative that could only exist by design.
