Over on his excellent blog, Worship Matters, Bob Kauflin has been posting recordings of worship songs from the 2008 Na conference in Louisville. The musical worship was led by his son Devon. Listen here + here.
“All I Have is Christ” (off this excellent new album) is a personal favorite:
Thanks for sharing these recordings, Bob!

It’s a great song. I loved singing it back in April when I visited Covlife (on the way to T4G), and it’s cool to be able to hear it again and share it with others.
