If the [biblical] story is true, Jesus Christ is the interpretative key to every fact in the universe and, of course, the Bible is one such fact. He is thus the hermeneutic principle that applies first to the Bible as the ground for understanding, and also to the whole of reality. Interpreting reality correctly is a by-product of salvation. Thus we must assert that the person and work of Jesus Christ are foundational for evangelical hermeneutics. … Christ interprets all facts, since all things were created in him, through him and for him (Col. 1:16). As the one mediator between God and man (1 Tim. 2:5), Christ mediates the ultimate truth of God about all things and thus about the meaning of the Bible.
