Today we celebrate the Festival of Reformation. And it will be more than a celebration. It will be a call to war, a call to sing, a call to celebrate even before the final victory. Yes, it’s true. We’re in the middle, between the not yet and the already of our salvation. Yet, we sing as those who are confident of the victory. God taught his people to sing and even gave them songs to sing even before they came home from exile. Jeremiah 51:54-64.
