This year marks the five-hundredth anniversary of the beginning of the Reformation. Martin Luther ignited the Reformation when he nailed his Ninety-Five Theses to the door of the Castle Church in Wittenberg, Germany, on October 31, 1517, calling the church to repentance and to return to the gospel. The flame that Luther ignited in Wittenberg spread like wildfire throughout Europe and around the world. Just as the Apostles turned the world upside down with the gospel, Luther set the world ablaze with the gospel. But ultimately, it was neither the Apostles nor Luther who did it; it was the Word of God and the Spirit of God that did it all.
