Training is Christ's
design for His Church.
In Ephesians 4:11-13, Paul states that the role of church leaders is "equipping the saints for the work of ministry." The result, he says, is unity and maturity. Training, then, is essential to both the design and health of the Church. In the same way you wouldn't loan your car to someone without a license, why would we trust the sacred work of Christ's Church to untrained volunteers?
Healthy churches must practice leadership development—not placement—as they equip their people. But successful training requires a combination of knowledge on how to do the work, experience doing the work, and coaching from a godly leader.
