John Piper’s Lecture at Westminster Theological Seminary on New Calvinism and the New Community

I found this talk very helpful, delivered March 12, 2014, at the seventh annual Richard B. Gaffin Jr. Lecture on Theology, Culture and Missions at Westminster Theological Seminary in Philadelphia. The title of the lecture is “The New Calvinism and the New Community: The Doctrines of Grace and the Meaning of Race.”
