This is the video of David Platt as he addresses the students and faculty of Liberty University in February, 2011. At the beginning of the sermon, he says as his purpose:
"I want to call you based on the authority of God's Word to abandon your plans and your dreams and your ideas, your possessions, all of your hopes of living out a nice, comfortable, middle-class American Christianity. I want to call you to abandon it all to make the glory of Christ known among every nation in the world."This sermon has been archived into three videos that I have posted below.
