On October 31, 1517, Martin Luther nailed 95 theses to the church door in Wittenberg, Germany and effectively began the Protestant Reformation. 499 years later, we still celebrate and experience the benefits of that Reformation which helped restore the church to the foundational teachings of the Bible. In this sermon, we talk about the most significant principles that were reintroduced by Luther and the other Reformers: Scripture Alone, Grace Alone, Faith Alone, Christ Alone, and God’s Glory Alone.
