Dr. Andrew Jackson is one of the leading scholars on biblical history of Turkey, where Pastor Mark will lead a trip this coming June. Watch Part 1 of the interview here. Two-thirds of the New Testament is written to or from peoples in Turkey, but less than 1 percent of all Greco-Roman sites are excavated today. "This is like an open museum that you can travel through and experience," says Dr. Andrew Jackson, who's visited the country over 200 times for research and to lead tours through Turkey's biblical historical sites. In this clip, Dr. Jackson explains how the seven churches of Revelation were not written in a random order, and Ephesus was in fact a very strategic location for the movement of the gospel. Dr. Andrew Jackson is the author of several books, including the Mormonism Explained and 30 Days Turkey Prayer Guide.
