Bill and Glenda Davis work alongside the Mutzke family in Heidelberg and are involved in both church and school ministries. Bill’s church involvement includes regularly-shared preaching, shared teaching of the adult Sunday school class, holding young adult meetings and biblical counseling.

The Davises both regularly disciple new believers and counsel others. Bill and Glenda began a children’s church ministry and were able to involve and hand it over to the Germans. A special joy for Bill is helping men in their teaching and preaching in Sunday school, children’s church, youth group, young adult meetings and Wednesday evening meetings. The Davises also work in the organization and execution of the church's summer and winter retreats.

The Davises are extensively involved with outreach ministries through monthly distribution of gospel tracts and other literature in downtown Heidelberg, organizing and participating in school Christmas programs, and monthly nursing home ministries. They oversee hospitality and the logistics of visiting ministry groups or individuals. A special delight for them is involvement in the choir, weekly small church orchestra and special programs. They consider it a privilege to minister to students of the University of Heidelberg, Germany's oldest University and home to students from many nationalities.

Bill is on the Christian school board, oversees the building maintenance and purchasing, and supports the Mutzkes by counseling and advising teachers and parents. Glenda and school parents put on the “Teacher Appreciation Banquet” at the beginning of each school year so the graduating class can spoil their teachers royally at least one night of the year.

The Davises have seven children: Heather is on staff at BJU and slowly pursuing another advanced degree in church history, Dawn, after finishing a masters degree in counseling, is now married and serving the Lord with her husband in Wisconsin, Crystal is teaching in a Christian school in Greenville, Heidi started BJU in the fall and William, Anna and Carolina are helping and involved in the ministry on the field.
