Query: EXCELLENT PRODUCT!

I FIND THIS CD SERIES EXTREMELY USEFUL. I'M TEACHING A BIBLE STUDY ON THE PURPOSE-DRIVEN LIFE & FIND THIS VERSION A WONDERFUL TOOL TO RECAP EACH CHAPTER. WISH I HAD THESE CD'S THE FIRST TIME I TAUGHT ON THE SUBJECT!GOD HAS USED RICK WARREN TO SOW WONDERFUL SEEDS IN COUNTLESS LIVES--INCLUDING MINE. I'LL BE ALWAYS GRATEFUL FOR THE NEW DIRECTION I'VE FOUND BECAUSE OF HIS WORK! THE CD'S ARE A CONSTANT ROAD COMPANION TO ME.
