"Singleness of Heart is an experientially deep yet sophisticated treatment of the dynamics that constantly hinder a simple and straightforward doing of the good for God's sake. This book will help those who seek liberation to find God's provision for a life of integrity in Christ."
--Dallas Willard, Professor of Philosophy, University of Southern California
"Clifford Williams writes with the acuity of a philosopher and the seasoned faith of a deeply reflective believer. This book restores the soul."
--Cornelius Plantinga Jr., President, Calvin Theological Seminary
"Williams offers the seeker a penetrating look at our tragic, ongoing separation from God, and suggests how we might change the focus of our attention if we truly want to come near to God. Those willing to exchange the comfort of routine for the promise of grace will be grateful for his thoughtful analysis."
--Jim Antal in Weavings: A Journal of the Christian Spiritual Life
