He focuses on the doctrine of the atonement, exploring the many ways in which the death and resurrection of Jesus Christ effect the reconciliation of all things to God. In addition to biblical, theological and historical studies of this doctrine, he enjoys exploring the contribution of literature and other fields to this topic. He is the author of Gods Being in Reconciliation and Atonement: A Guide for the Perplexed, and editor of the forthcoming T&T Clark Companion to the Atonement, all with T&T Clark.
