This indispensable guide to the search for kinship with God was written by the great nineteenth-century Danish philosopher Soren Kierkegaard (1813-1855), whose writings set the stage for existentialism and continue to exert a lasting influence on believers and nonbelievers alike. Kierkegaard struck out against all forms of established order--including the established church of his time--that work to make men complacent with themselves and thereby obscure their personal responsibility to encounter God. He considered Training in Christianity his most important book. It represented his effort to replace what he believed had become 'an amiable, sentimental paganism' with authentic Christianity. Kierkegaard's challenge to live out the implications of Christianity in the most personal decisions of life will greatly appeal to readers today who are trying to develop their personal integrity in accordance with the truths of revealed religion.
