"From a Christian perspective, God is not a "thing", an object that exists like the desk I am sitting at exists, but a person with whom I am in a vital relationship. "Knowing" is not of the same order as knowing an electron, a chromosome or a galaxy: this presupposes a theoretical model and objective experimental verification. Proving the existence of the atom is one thing, but the same procedure cannot be used for the God who revealed himself in Jesus Christ. The relationship I form with him is about freedom."
