of the Century in 2001. Other popular Card songs include Immanuel, Joy in the Journey, and Heal Our Land. Heal Our Land was commissioned as the 1993 National Day of Prayer's theme song. Despite his success in music, Card has always maintained that his music career is secondary to his calling as a Bible teacher. He has distanced himself from the CCM industry by criticizing the promotion of personalities over musical content and the shifting emphasis away from God to sell more albums. In 2008, alongside the By/For Project, Card produced and contributed vocals and songs to the album Sweet Sacrifice, collaborating with Seattle, Washington based artists Brian Moss, Molly McCue, and Kurt Dyrhsen. The album was made available for free on ByFor.org under a Creative Commons Attribution license. In 2019, Card released the album, To the Kindness of God, featuring 7 new original songs, 2 hymn covers, and one new arrangement of one of Card's earlier songs, "Song of Gomer" (here renamed "Gomer's Song"), which first appeared on the album The Word: Recapturing the Imagination. Prior to its release, Card announced that it would be his final full-length album, but also clarifying that he was not yet retiring from music in general, or writing new music. Author Michael Card is the author or co-author of twenty-two books. He originally started writing as a way to share the knowledge he accumulated while researching his songs. He found his studies were too in-depth to condense everything he had learned into one short piece. The books that resulted from album research bear the same titles as the albums. He then branched out to other subjects not specifically based on his music, such as the Gospel of John, homeschooling, and Christian discipleship and mentoring. In 2014, Card completed the Biblical Imagination Series, a four-volume set which takes a deeper look at each of the gospels and the voice of the writers behind them. He followed up on the Biblical Imagination Series next by releasing a new book (and album) on the subject of the Hebrew word (ḥesed), an idea which he first explored in his two books on lament (A Sacred Sorrow and The Hidden Face of God). The book is about the bibliography of the word throughout the Old Testament, and how we can start to understand this word that is so often used to describe God and cannot be precisely expressed
