The feeling of being, or not being, forgiven and loved, is not what matters. If there is a particular sin on your conscience, repent and confess it. If there isn't, tell the despondent devil not to be silly. One must always get back to the practical and definite. What the devil loves is that vague cloud of unspecified guilt feeling (or unspecified virtue) by which he lures us into despair (or presumption). 'Details, please?' is the answer. The sense of dereliction cannot be a bad symptom, for our Lord Himself experienced it in its depth – 'Why hast thou forsaken me?'”
