The law and prophets are often typological presentations of the coming Messiah. In the NT Jesus explained the law of Moses and the prophets and Psalms were full of references to Him and that the entirety of those texts was about Him. In other talks I highlighted the Theophanies in the OT who are none other than the Logos, the Second Person. The appearances to Elijah and the symbolism in these texts are often overlooked as prophetic types that attest to inspiration.
