Tim Huges says it best in "Consuming Fire"

There must be more than this
O breath of God come breathe within
There must be more than this
Spirit of God we wait for You
Fill us anew we pray Fill us anew we pray

CHORUS:
Consuming fire fan into flame A passion for Your name
Spirit of God fall in this place Lord have Your way
Lord have Your way with us

Come like a rushing wind
Clothe us with power from on high
Now set the captives free
Leave us abandoned to Your praise
Lord let Your glory fall, Lord let Your glory fall
