This week instead of posting a quote from Martin Luther, I am posting video of three lectures on Martin Luther by Carl Trueman, who is a church historian at Westeminster Theological Seminary. He gave these lectures last month at Southern Baptist Theological Seminary.
Martin Luther as Theological Pastor: Theological & Biographical Foundations
Martin Luther as Theological Pastor: The Word in Action
Martin Luther as Theological Pastor: Tools of the Trade
