"There's just nothing we can do without grace; we?re all dirty, messed up people, but Christ still loves us," Rhett Walker says of the drive behind "Come To The River". "So there?s two things we must do. One: rejoice, because now we have a purpose on this earth - to share that grace with others. Two: take up the calling. You can?t just take that love and not tell the story that goes with it."
