Our History

Operation Mobilisation traces its roots to the prayers of an American

housewife. In the 1950s, Dorothea Clapp began to pray faithfully for

the students in her local high school. She asked God to touch the world

through the lives of the young people. And God answered her prayers.


Mrs. Clapp’s son gave the Gospel of John to one of the students, who later gave his life to the Lord at a Billy Graham meeting. That young man was George Verwer, the founder and International Director of Operation Mobilisation. At college, George and two friends met regularly to pray. They became burdened by the spiritual needs of Mexico.


The three friends sold some of their possessions to raise money and gave up their summer holiday to distribute Gospels and other Christian literature in Mexico. The friends returned to Mexico the following summer and the next.

When they graduated, George and his friends traveled to Europe. They began work in Spain, sharing the Gospel and distributing literature. But the task of reaching the whole of Europe seemed overwhelming. George and his small team realised that God’s plan was to mobilise His Church to reach the nations. As they began to share their vision, hundreds of Christians responded. So a movement called Send the Light was born.


2,000 Christians had joined summer outreach teams in Europe. At the same time, teams moved into the Indian sub-continent and the Muslim world. Their commitment was to reach those who had never heard the Gospel.

Ministry begins spreading around the globe via the Logos ship in 1970 and the Doulos ship in 1977.
