Mark and Gail McKeller were longtime members of The Brooklyn Tabernacle serving in a number of ministries, but with a focus on youth and children's ministry. Over several years, the Lord began to give them a heart for Native American ministry in Arizona. They began to pray and consult with Pastor Cymbala, and in 2004, they went to Arizona.
For two years, they served at a predominantly Native American church in Phoenix, working in young adult and children's ministries as interim associate pastors. In 2006, the McKellers joined Broken Arrow Chapel on the Navajo Reservation where they have remained. Officially called the Navajo Nation, it is the largest reservation in the United States.
At the church, they are the youth pastors, teaching Sunday School, leading Friday night youth meetings, and directing the summer kids and youth camps. Many of the teens and children Mark and Gail serve come from troubled homes. This includes homes where parents (one or both), or a close relative to the family, are alcoholic. Most are poor— far worse than what is commonly seen in urban or mainstream America. Some families struggle mightily to have food to eat and could spend considerable time without electricity or running water.
Mark and Gail desire to see the young people develop into mature believers in Christ, assisting at their local churches and being used by God as ministry leaders throughout the Navajo and other reservations and to the ends of the earth.
