This episode is part one of a two-part conversation with Indian American theologian, Dr. Sam George. He’s the director of the Global Diaspora Institute at Wheaton College Billy Graham Center, Illinois, and has authored and edited twenty books and numerous journal articles. Sam studies and teaches how the movement of people impacts Christianity.

In this episode, Sam talks about how his background as an immigrant from the Andaman Islands of India shaped his faith and why he left a successful career in the corporate world to pursue seminary studies. Sam served on the leadership of the Lausanne movement from 2016 to 2025. He witnessed hundreds of refugees come to Christ while he traveled to Europe, Asia, and Africa to study the refugee crisis.

Sam explains the important connection between migration and theology, pointing out that the Bible is a story of migrants or displaced people and that Christianity is a moving, missionary faith.
