Verwer's first contact with Christianity was through his neighbor, Dorothea Clapp, who gave him the Gospel of John and also put him on her "Holy Ghost hit list". Verwer attributes to her some of the reason that he made a commitment to Christ, and for what resulted in his life.

When he was a pupil at Ramsey High School in New Jersey, he went to a "Jack Wyrtzen" meeting in which Billy Graham spoke in Madison Square Garden, in New York City. There he was converted to become a Christian, at the age of 16. Within a year, about 200 of his classmates became Christians.

He had a growing conviction to evangelize on foreign soil. He started with distribution of the Gospel of John in Mexico in 1957 along with two friends, Walter Borchard and Dale Rhoton. They called this operation "Send the Light". This continued with others during summer holidays. Afterward, Verwer used the name "Send the Light" for a book distribution operation to India based in the United Kingdom. This has since developed into Send the Light, the largest Christian book distributor in the United Kingdom.

After high school, he attended Maryville College and then transferred to Moody Bible Institute, where he met his wife, Drena, who was a fellow student.Commencement Speaker, Conferred an Honorary degree, Doctor of Divinity, May 22, 2009 at Biola University.

After graduation, they went to Spain. Once while taking Bibles into the USSR, George was arrested and accused of being a spy. He was deported, and back in Spain, after a time of prayer in 1961 the work of Operation Mobilization (OM) was born. George often refers to this calling himself "God's Bungler", in reference to Brother Andrew, "God's Smuggler".

In August 2003, George handed over the international leadership of the work of Operation Mobilization to Peter Maiden, who was the Associate International Director for 15 years. George and his wife are now involved in Special Projects Ministries full-time. They still travel and take meetings around the world.

Drena and George had three children. Although born American, George became a naturalized British Citizen, and they live in Kent.
