Despite achieving fame as a beloved country music artist, Cash developed a dependency on amphetamines and barbiturates, which started in the ‘60s. It would be Carter, who not only encouraged him to seek treatment, but also helped him rediscover his connection to Christianity. The patriarch recorded several religious albums, and the couple even traveled to Israel for the film "The Gospel Road." It was later acquired by the Rev. Billy Graham's film company.

For Carter Cash, his parents’ connection to their faith was ever-present at home. The Grammy-winning singer/songwriter, 52, is now hoping to share that wisdom passed down to him. The John R. Cash Revocable Trust, in partnership with DaySpring Books, has released "Walking the Line," a collection of 90 devotionals, and never-before-seen content from Cash, centered around his faith.
