Francis A. Schaeffer founded the L'Abri Fellowship in Switzerland and was the author of many books, including The God Who Is There. Until his death in 1984, he was also a noted speaker with a worldwide ministry. His ministry continues through his books, with over two million copies in print.

In a career that spans 30 years, Michael Card has recorded over 31 albums, authored or co-authored over 24 books, hosted a radio program, and written for a wide range of magazines. An award-winning musician and performing artist, he has penned such favorites as "El Shaddai," "Immanuel" and many other songs. He has branched his ministry beyond music and written numerous books, including A Sacred Sorrow, A Violent Grace, The Parable of Joy and Sleep Sound in Jesus (a children's book). He has also written the Biblical Imagination Series, with a book and accompanying music CD for each of the four gospels.

A graduate of Western Kentucky University with a bachelor's and master's degree in biblical studies, Card also serves as mentor to many younger artists and musicians, teaching courses on the creative process and calling the Christian recording industry into deeper discipleship. Card lives in Tennessee with his wife and four children.
