That which is true will always expose that which is untrue or corrupt. That is exactly what took place when Martin Luther placed God's Word as a filter over the practices of the Roman Catholic Church in the 16th century. From his efforts, along with others, came the Protestant Reformation. When the Bible is held as the chief authority, all that which is untrue and corrupt crumbles. In our current culture, there are lots of voices declaring themselves as true and authoritative. How do we know who or what to believe? The answer is really quite simple, we do what Luther did. We use God's Word as a filter and see what shakes out. We'll talk about how, in week 2 of The 5 Solas.
