I'm not the type of person who usually bothers to endorse devotional books, but I have had the opportunity to read FOR THE LOVE OF GOD (vols. 1 and 2) by D.A. Carson and consequently, I've been endorsing it to Christians from all walks who take their relationship with God very seriously. These devotionals attempt to return the focus back to Scripture, not the comments of the devotional writers. It also attempts to give the reader the "bigger picture" of Scripture (i.e. the whole counsel of God), so that one's vision would not be constrained to passages and verses, something that might give the impression that the Bible talks about many unrelated things. This approach clearly sets it apart from many devotionals.
