Brother Wilson was one of the earliest members and pastors of the BMA. He founded the Bethel Church in Hatfield, Indiana which is still operating today, now pastored by his son, Rev Jim Wilson. Brother I.E. Wilson, along with Rev R. R. Schwambach and others had the original vision for Bethel Youth Camp, leading to its purchase in 1954. Moving from their previous Youth Camps in Nazarene Acres in Illinois, the camp has inspired hundreds of youths for decades and been instrumental in inspiring missionaries and pastors to locations around the world.
