On October 31, 1517, Martin Luther posted his 95 Theses on the church door in Wittenburg, Germany. This has been traditionally observed as the beginning of the Protestant Reformation which has drastically altered the course of Western Civilization and culture.
As a former PhD student in Reformation History, I love to think of Luther and the other reformers. Their impact has been tremendous.
The 95th of the theses is:
And thus (being diligent in following Christ) be confident of entering into heaven rather through many tribulations, than through the assurance of peace.
