Attorney Mark Hitchcock thought his career was set after graduating from law school. But after what Mark calls a "clear call to full-time ministry," he changed course and went to Dallas Theological Seminary, completing master's and doctoral degrees. Since 1991, Mark has authored numerous books, serves as senior pastor of Faith Bible Church in Edmond, Oklahoma, and is also an Associate Professor of Bible Exposition at Dallas Theological Seminary. Mark and his wife, Cheryl, live in Edmond with their family.
