Spiritual Depression

I am aware of no better resource for the spiritually depressed than Martyn Lloyd-Jones' now famous sermon series on Spiritual Depression.  When I've sunk for an extended time (not just for a day or two), I've often turned to this resource and have always found encouragement and light.  In fact, I just read another chapter today (after not touching the book for probably a year) since I'm going through an unusually dry and dull season.  And, again, I got help.  I highly recommend it.
