The story ends with Cash singing with weakness and humility. It ends with God’s grace being perfected within him. It ends with him having solidarity with Jesus.
The song uses the physical presence of Greystone Chapel as a metaphor for the vibrant spirituality that can be found within prison. It is a song about how a person’s mind who is aligned with Jesus can transcend his physical circumstances. In this way, the song echoes Paul’s observation that “where the Spirit of the Lord is, there is freedom.” 2 Cor. 3:17.
