Dr. Seif was born into a German-Jewish family and was raised in a typical American Jewish household, save for the fact that he was sent off to go to school in a Yeshiva—an Orthodox Jewish training school. Though raised with a “traditional” Jewish upbringing, Jeff eventually came to a saving faith in Jesus, subsequent to which he experienced a “call” into vocational Gospel ministry. Jeff eventually went to school to prepare for the ministerial vocation, taking studies at the Moody Bible Institute, Trinity College, the Graduate Theological Foundation and then the theological Seminary at Southern Methodist University where he received both a master’s degree and doctorate. Jeff served as a missionary with the American Board of Missions to the Jews, and has held pastorates and other ministry posts for well over twenty-five years.
