"If the Churches of Christendom are to reach the Moslem World with the Gospel, they must know of it, and know it."-Samuel Zwemer

Zwemer Center for Muslim Studies

The Zwemer Center at Columbia International University exists to offer comprehensive courses on Islam, facilitate research, foster dialogues, offer seminars, conduct training and provide resources for effective witness and ministry among Muslims. Those who want to study Muslim missions will benefit from the Zwemer courses offered in the Master’s Degree in Muslim-Christian Relations.

Founded in 1979 at the U.S. Center for World Mission, the Zwemer Institute became a major resource and training center for Christians seeking to engage Muslims with the gospel. This need was highlighted with the emergence of the Lausanne Movement and grew out of a consultation led by Dr. Don McCurry, the first Zwemer Director.

Multitudes of missionaries, missionaries-in-training, students and scholars have contributed research, studied in seminars and earned graduate degrees in Islamics over the years, facilitated by the renowned faculty and adjunct staff. Hundreds of churches have been equipped to understand and relate to Muslim neighbors in seminars conducted throughout North America… Read More

Cash Godbold Retired Missionary

North Africa

Full Bio

Cash Godbold

Cash and Ann are true pioneer missionaries, living for 30 years in the Sahara Desert working with the Tuareg people. They grew up in Columbia, attended Columbia International University, and married in 1958. Leaving for the mission field in 1960, they raised 3 children in severe and primitive conditions. Their love for the Tuareg was obvious in their adaptation to their ways, dress, food, and customs. Their continuing work is a strong testimony to the missionary call, conducting workshops on the mission field and the US teaching believers how to witness to the Muslim people. Cash and Ann have been used mightily to stir the hearts of churches and young people for the cause of missions. Each of their three married children attended CIU and has spent time on the African mission field.
