Pastoral Ministries

The Potomac Conference Corporation Pastoral Ministries Department provides resources to help our pastors and churches grow by emphasizing mission, vision, and values. Everything rises and falls with leadership. The Potomac Conference Corporation seeks to create an environment where our pastors have the opportunity to grow as servant leaders, both spiritually and professionally. Pastors, called by God, “prepare God’s people for works of service, so that the body of Christ may be built up” (Ephesians 4:12­13 NIV). The pastor trains and equips their members to faithfully use their spiritual gifts to minister and make disciples within their communities.

The importance of spiritual and numerical growth cannot be underestimated. Both are vitally important for the health of the church. One of the most important ways to evaluate this growth is through church consultations. These consultations are like annual physical check­ups. The benefits are similar to a good prescription: they lead to a healthy, disciple-­making church with a clear mission and vision. We pray daily for the Holy Spirit to lead and guide our pastors. Our pastors are not alone ­ we are on this journey together.
