Who We Are

What is BIBM?
BIBM serves as the LINK between the local church, the missionary, and the mission field. Jesus commissioned the local church to “go ye into all the world, and preach the gospel to every creature (Mark 16:15)”. BIBM bridges the gap between the local church, their missionary, and the mission field. When a missionary family and their local church partner with BIBM, they are properly prepared for deputation, relocating to their mission field, language study, cultural adaptation, evangelism, discipleship, planting churches, and training the next generation for ministry so the work continues in perpetuity. In addition, our office helps with all the details for a successful furlough.
Why BIBM?
BIBM is built on the biblical model of missions and provides the assistance that every church, pastor, and missionary family needs to stay connected and accountable.
- Financial: BIBM has an office located in Johnson City, Tennessee. The office, named the Mullendore Missions Headquarters, provides extensive benefits to the church and missionary family. BIBM has a system to track monthly financial support, provide monthly financial statements of church giving, pay expenses while the missionary is on the field or on deputation, and transfer funds to the missionary for both projects and living expenses. This is done while maintaining proper financial records to pay taxes for the missionary family, and report all missionary earnings to the IRS. BIBM provides the church and the missionary with the greatest potential for good stewardship with the Lord’s provision.
- Ministry: The Executive Director, Missionary Adam Crabtree, maintains constant contact with the BIBM missionary families. His vision is to see every pastor involved in the church planting work of his missionary and for the fruit of the missionary’s labor to be a shared with his sending church. BIBM does not replace the role of the sending pastor or the authority of the sending church. All matters of ministry including direction and discipline are matters that are reserved for the local church to handle. The director is able to help the pastor and the missionary. With his years of experience, both domestic and abroad, he is a valuable resource. BIBM reserves the right to part fellowship with a missionary who is in violation of the policies and procedures or ceases to be in agreement doctrinally with this ministry.
- Government: BIBM takes the financial burden from the local church. The office staff provides proper accountability for funds given. BIBM stays informed of the local news from around the globe to better serve the missionary family. The director and his family served in Greece during a volatile time and he understands the importance of maintaining contact during uncertain times. Safety is a primary concern with BIBM. There can be complications with wire transfers, exchange rates, residency/missionary visas, missions trips, furloughs, and shipping ministry supplies. The BIBM office has extensive knowledge and experience that can help each missionary family, no matter their field of service.
