Upcoming Sunday, 31 October, is `Reformation day'. We will read, sing and listen to Psalm 46. It was Martin Luther's favourite Psalm. His time was a time of great anxiety. Thousands died because of the plague. Wars broke out. Luther was declared an outlaw. He found a hiding place in a fortress: the Wartburg. Based on Psalm 46, he wrote his famous song `a mighty fortress is our God'. But how could he sing, feel safe, keep joy and peace, while so much was going on? This had everything to do with his rediscovery of the biblical good news - the Gospel. Luther's discovery is still as powerful as it was in his time.
