Over the past month I've posted a few meditations from Paul's Tripp's book Whiter than Snow, a book of 52 meditations on Psalm 51.
I enjoyed that book so much that I picked up a copy of Tripp's other similar book of meditations on Psalm 27, titled A Shelter in the Time of Storm. Here's a book trailer:
I'm almost halfway through the book, and I'm also finding this one encouraging, penetrating and insightful. Highly recommended!
