'Sometimes, in bitterness of temptation, when the spirit struggles with a sense of God's anger, we are apt to think God an enemy. A troubled soul is like troubled water: we can see nothing in it, and, so far as it is not cleansed, it will cast up mire and dirt. It is full of objections about itself, yet for the most part we may discern something of the hidden life, and these smothered sparks. In a gloomy day there is so much light that we may know it to be day and not night; so there is something in a Christian under a cloud whereby he may be discerned to be a true believer and not a hypocrite. There is no mere darkness in the state of grace, but some beam of light whereby the kingdom of darkness does not wholly prevail.'
Richard Sibbes, The Bruised Reed, p.37.
