One hammer in the hand of an obscure Augustinian monk changed the world forever.

Martin Luther posted his Ninety-Five Theses on the church door in Wittenburg, Germany calling his fellow professors to examine issues of supreme theological importance. Thus began the Reformation through which the light of God’s Word was brought out of the darkness to shine with clarity once more. 

The Reformation was more than standing against the Roman Catholic Church.  It was about standing for the gospel of Christ.
Luther made his stand for the glory of God.

In every generation the gospel must be published anew with the same boldness, and the same clarity, and the same urgency that came forth in the 16th century Reformation.
