Gordon Graham on imagination in worship
The greatest poetry is an imaginative achievement, not a biographical report. It would be absurd to think, for instance, that Shakespeare had to experience all the jealousy, ambition, love, despair, remorse, paranoia, light heartedness, or grief that he powerfully depicts in the poetry of his plays. It is his astonishing, and seemingly unlimited power to give imaginative expression to these many states of mind without having experienced them, that constitutes his unsurpassed literary gift.
So too with religious poems and hymns. When ordinary worshippers sing some of the finest Christian hymns, for instance, the religious sentiments expressed often far exceed their own. They may also exceed the religious sentiments of those who wrote the hymns. Contrary to what is often supposed … this need not imply either insincerity or a lack of understanding. Religious worshippers set their sights on higher things, hoping to connect with something that transcends ordinary experience. Emotional elevation by means of hymns, poems, and prayers that imaginatively express ideals of feeling play an important part in this endeavor.
