Five centuries after Luther nailed his Ninety-five Theses to the door of a Catholic church, is there still a need for reformation? Yes, the Reformers' 'Five Solas' - Scripture Alone, Christ Alone, Grace Alone, Faith Alone, the Glory of God Alone - should be engraved on all our hearts, and the need could hardly be greater for them to be nailed to the doors of today's shallow churches today that are in danger of "being destroyed for lack of knowledge" (Hosea 4:6).
