As one person already said, this film is a modern day retelling of the parable of "The Prodigal Son". David definitely is the younger son who runs away and lives a life of sin while Frank is the older brother who stays behind and who tries to live a righteous life. However, the twist in this is the fact that even though Frank is now the the head of his church he has forgotten that his main mission is to spread the word of the Lord. However, he uses his position to pretty much alienate everyone, including his wife. This film pretty much looks as if it pretty much speaks to a lot of people on a lot of different levels. One is obviously the music and the other is the moral dilemmas that many of us face in our lives. It also takes a hard look at a lot of preachers out there who, like Frank, use their positions to promote themselves and don't care about the needs of their congregations. This is truly a good film and it definitely has a very uplifting story.
