The Psalms are, as it were, the anatomy of a holy man, which lay the inside of a truly devout man outward to the view of others. If the Scriptures be compared to a body, the Psalms may well be the heart, they are so full of sweet affections and passions. For in other portions of Scripture God speaks to us; but in the Psalms holy men speak to God and their own hearts.  – Richard Sibbes in The Soul’s Conflict with Itself
