Audio on the cross

I have recently come across several audio sermons that deal with themes related to the cross that I have found exceedingly helpful and encouraging.

At the recent Together for the Gospel conference, virtually all the speakers dealt with topics related to the cross and the atonement; I found particularly helpful the messages by Al Mohler, R. C. Sproul, and John MacArthur (though they were all excellent and worth listening to more than once).

I have also listened to a couple sermons lately by C. J. Mahaney, and been reminded how effectively he communicates themes about the cross. One three-part series that he did at Covenant Life Church is "Christ and Him Crucified."
