Singleness of Heart is an invitation to explore the spiritual dividedness that infects the Christian heart. Writing for those who feel themselves being pulled in opposite directions spiritually, Clifford Williams probes spiritual dividedness to reveal the concealed and unacknowledged motives that undermine the search for inner peace. Drawing judiciously on the work of writers like Augustine, Dostoevsky, Ernest Becker, Pascal, Tolstoy, Kierkegaard, and the Apostle Paul, Williams describes two kinds of spiritual dividedness: ambivalence, in which we are both attracted to and repelled from a given object, such as God's love; and illusion, in which the motive we think we are acting from differs from the actual motive. He also poses two avenues of spiritual restoration: being open to God's mercy and being involved in a community of grace. A challenging but much-needed book for Christians across a broad spectrum - from laypersons and students to pastors and Christian philosophers - Singleness of Heart systematically yet gently searches the secret places of the Christian heart, taking readers beyond the cursory acquaintance they often have with their true selves and leading them to the healing power of God's grace and the "single-minded pursuit of eternity".
