The Psalms were where I headed when God finally helped me -- a tired and overwhelmed mother of three little boys -- realize that I *needed* the milk and meat of His Word as much as my sons needed the physical milk and meat I set before them each day. I was starving.
As I learned to read and study, my experience confirmed the truth of the Psalms' opening words. The man (or woman) who delights in God's Word is blessed. He's happy. He is at peace.
