Mere Christianity

In plain language, the question should never be, "Do I like that kind of service?" but "Are these doctrines true: Is holiness here? Does my conscience move me towards this? Is my reluctance to knock at this door my pride, or my mere taste, or my personal dislike of this particular doorkeeper?" ...And above all you must be asking which door is the true one; not which pleases you best... -from the Preface of Mere Christianity
