John and Teresa Musser founded Gospel Revival Ministries in 1980 as an itinerant evangelism ministry. They have traveled to some of the most remote and dangerous regions of the world reaching the lost at any cost.

GRM has now grown into a global ministry reaching the last of the lost (unreached people groups) in highly restricted areas where there is little or no missionary activity,

freeing entire Christian families born in brick makers prison in Pakistan, equipping hundreds of Christian women in Pakistan through the Teresa Sewing Centers, and

feeding, equipping, and church planting among the poorest of the poor in Haiti.

GRM works with a network of over 1,100 native leaders with a major focus in India, Haiti, Pakistan, and beginning a work in Bethlehem, Israel. We also have a long and great history in northern Nigeria, the Sudan, and Niger. Many years and great breakthroughs were spent in northern India in Nagaland with ministry into Nepal, Burma, Bhutan, and Bangladesh.

John and Teresa have been married for 44 years. They have four children and 13 grandchildren. They celebrated 45 years in ministry together, 45 years of marriage, and have an upcoming 43 year anniversary for GRM in June 2023!
