There Must Be More Lyrics

Lord I groan, Lord I kneel.
I'm cryin' out for something real.
'Cause I know deep in my soul
There must be more!
Lord I'm tired, yes I'm weak -
I need your power to work in me.
But I can't let go, I keep hanging on -
There must be more!
There must be more!
River flow; fire burn.
Holy Spirit breathe on me.
