I don't know whether Lee Greenwood is a Christian or not, but his song God Bless the U.S.A. can bring a tear to my eye because it's coupling faith in God with patriotism for my country the United States of America. Some Christians when they sing the song change Lee's original lyrics of "I thank my lucky stars" to "I thank my God above" because of the superstition of "lucky stars" and of not acknowledging God instead. Here's Greenwood's story of how he wrote the song and his experiences singing it before presidents.
