Spiritual Revolution tells the compelling story of 50 years of Operation Mobilisation (OM), today with more than 5000 workers in over 100 countries. Beginning with George Verwers conversion as a teenager in New York City, the story traces Gods faithfulness from the first outreach in Mexico City to OM becoming one of the worlds largest mission agencies. Stretching from India to Latin America, OM has pioneered short-term missions, ships for world evangelism, and has been at the cutting edge of the explosive growth of missions from the global church. This is ground-breaking history.
