Music directors or song leaders need to have a pastoral approach to the whole church, exhibiting warmth and humility and being able to inspire confidence about singing together, learning new songs and enjoying the contributions of musicians and singers. The glory of the gospel is to unite peoples of every language and culture under the lordship of Christ (Eph. 2:11-22; 4:3-6,13; Rev. 7:9-17). So we should not be content with divisions created by different musical tastes and traditions. As we grow to maturity in Christ we should be looking for ways to express the unity that is God’s goal for us: in gospel action, in the exchange of ministries and gifts, in combined services and in the sharing of musical resources and experiences.
