You've got to listen to this song! Terrific. It's a powerful song about the grace found in Christ and what the church should be all about. See Matthew 22:9: "Go to the street corners and invite to the banquet anyone you find." (HT: Immanuel Church)
The song's composer, Stuart Townend, also wrote the lyrics to the amazing hymn, In Christ Alone. He tells the story of "Vagabonds" below.
