Christianity is not a doctrine, not, I mean, a theory about what has happened and will happen to the human soul, but a description of something that actually takes place in human life. For ‘consciousness of sin’ is a real event and so are despair and salvation through faith. Those who speak of such things (Bunyan, for instance) are simply describing what has happened to them, whatever gloss anyone may want to put on it.
