• Johnny Cash struggled with drug issues throughout much of his music career. In 1968 he rediscovered his Christian faith, and subsequently ended all drug use for a time. However, by the late 1970s he'd began using amphetamines again, and by 1983 the singer had relapsed into addiction after being administered painkillers for a serious abdominal injury caused by being kicked by an ostrich he kept on his farm. That same year Cash entered the Betty Ford Clinic in Rancho Mirage, California for rehabilitation.
  
  Cash wrote this song about his faith while recovering from his drug addiction. His son John Carter Cash told NME: "Faith was empowering to my father, and you can hear his spirit being lifted up."
• A later recording of the song can be heard on the Rick Rubin produced posthumous album, American V: A Hundred Highways.
