We cannot compare the fact of Christ with other facts, nor can we deduce the fact of Christ from our knowledge of other facts. The fact of Christ comes breaking into the continuity of our human knowledge as an utterly distinctive and unique fact, which we cannot understand in terms of other facts, which we cannot reduce to what we already know. It is a new and unique fact without analogy anywhere in human experience or knowledge.
But let us note: it is only when we actually know Christ, know him as our personal saviour and Lord, that we know that we have not chosen him but that he has chosen us; that it is not in our own capacity to give ourselves the power to know him; that it is not in virtue of our own power or our own capacity that he gives us to know him, but in virtue of his power to reveal himelf to us and to enable us to know him; that is, faith itself is the gift of God. Or let me put that in another way: when we know God in Christ, we do not congratulate ourselves on our own powers of intuition or discovery, and pat ourselves on the back because we have been able to see that there is more in Jesus than meets the eye, that God is there himself. No, we do the exact opposite: we acknowledge that in knowing God in Christ, we do so not by our own power, but by the power of God.

For in him all the fullness of God was pleased to dwell, and through him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross. (Colossians 1:19-20 ESV)
