Let the systematic theologian spell it out. Let the artists throw out thoughts and slants, maybe even slants no one else has thought of. They should give another view of something familiar to help us learn more about it. They should deal with love, life, good, evil, God, the world and faith. Many of the biblical writers were poets more than they were theologians. Poets and prophets ranted and raved, and storytellers wrote great yarns that all had different slants on God and life and faith. Perhaps the poet's absence from the Church for many centuries has left it deprived of much insight.
