Experience With Dallas

Steve was a graduate student in philosophy under Dallas at USC from 1997-2003 and stayed in close contact with him from that time on.  He arranged for Dallas to participate in numerous conferences and events connected with Biola University, and worked with him on the board of editorial consultants of the Journal of Spiritual Formation and Soul Care, of which Steve is the managing editor. Knowing how passionate Dallas was about his work on The Disappearance of Moral Knowledge, Steve contacted the Willard family during Dallas's battle with cancer and offered his assistance, along with Aaron Preston and Gregg Ten Elshof, to complete the manuscript. Dallas's response to this offer was, "Now THEY could do it!"

Steve shared some of his personal memories of how the presence of Christ flowed through Dallas even as a philosophy professor in a secular university in Dallas Willard Remembered.
