The purpose of the church, or even religion itself, is often discussed in the modern world. As we listen to an admittedly "brutal Psalm" today in Psalm 79, what possible hope can we gather from Israel's defeat at the hands of Babylon in 586 BC? What we discover is a heartfelt reflection on something we admittedly misunderstand about God (his jealousy), something we love about what God can give (his forgiveness), and something we all cry for throughout the ages (his justice). But we learn something even more important - we learn about the community he is redeeming for the world and why it works still even today.
