The incarnation makes God tangible. It helps us think about God. It is quite astonishing how the question, ‘Is Christ divine?’ is discussed as if we had an excellent idea about what God was like, while Christ himself remained something of an enigma. But exactly the opposite is so obviously the case! Christ confronts us through the gospel narratives and through experience, whereas we have no clear vision of God. As John’s gospel reminds us: ‘No one has ever seen God; the only Son, who is in the bosom of the Father, has made him known’ (John 1:18). God is Christlike—in other words, we learn to think of God as we see him in Christ. For the Christian, it is Christ who provides us with the basis of the most reliable knowledge of God available.
