When people go to worship, whether in groups or alone, God designed them to need to exercise their imaginal intellect as much as any other dynamic of their being—including their rational intellect. When people worship God alone, they “practice” focusing their faith toward God through the gate of their imagination. As they couple their imagination with their intellect, they will imagine the unseen realities they "know" are true in Scripture.
When evangelization happens in its fullness, culturally appropriate and sensitive communication is crucial. In many parts of the world, due to lack of literacy, such communication will be through artistic or imaginative expression. Music, drama, storytelling, painting, architecture, mime, puppets, crafts, festivals, movement, ritual, and on and on, are all forms of artistic expression.
Do not see artistic expression as "secular." Don’t consider artistic expression as "worldly." As God created them they are reflections of His image in us; and in fact, it is our duty to dedicate them—all our imaginative expressions and efforts—to His glory and for His purposes . . . of reflecting His truth, and beauty, and reconciliation in Jesus!! (1 Cor. 10:31)
Most Christians have some sense that artistic methods, and artists themselves, could be and should be powerful sources of evangelistic efforts. But most artists and musicians will confirm that they feel most conventionally trained and serving church leadership doesn’t have the foggiest idea or vision of how to envision artists to be used; nor even possess the simple conviction to give artists and musicians permission to come up with ideas on how to engage the community around them for the sake of the Gospel. In fact, often musicians and artists will tell you that they feel that church leadership doesn’t really trust that they will get the “content” of the Gospel right, or communicate it well.
Artistic expression, as observed in the biblical record, is essential to life and Christian ministry—especially the worship ministries of the Church. This is because Artistic expression is the essential context wherein humans touch the transcendent realities of life in general, and most importantly, with God. Artistic and “imaginative” expressions—the metaphors, symbols, expressions, rituals, memorials, ceremonies, liturgies—form the amniotic fluid in which life and community grow and mature.
