Worship Leader and Pastor Bob Kauflin (Director of Worship Development for Sovereign Grace Ministries) has written a book called "Worship Matters" Published by Crossway Books) He also has a blog with the same title: www.worshipmatters.com/
He has 4 short intro videos to the different chapters in his book. I have yet to read his book (I hope to soon) but I recently heard him speak at a conference and have watched these video clips and find them fantastically helpful! So... I will post them here over the next few days! I'd love your thoughts!
The Leader(what do I love the most?)
