The Gospel is inherently and irreducibly confrontational. It cuts against our perceived righteousness and self-sufficiency, demanding that we forsake cherished sin and trust in someone else to justify us. Entertainment is therefore a problematic medium for communicating the Gospel, because it nearly always obscures the most difficult aspects of it – the cost of repentance, the cross of discipleship, the narrowness of the Way. Some will disagree, arguing that drama can give unbelievers a helpful visual image of the Gospel. But we have already been given such visual images. They are the ordinances of baptism and the Lord’s Supper and the transformed lives of our Christian brothers and sisters.
