A fellow named Jesse Larsen has put together a bunch of mp3 links from The Berean Call (a Christian radio show) when they have addressed the issue of Calvinism. There are a number of topics, most fairly short in length (under 10 minutes or so) He also has a link to a sermon by Bob Hoekstra entitled “The Sovereignty Of God And The Responsibility Of Man”. Good stuff.
The Berean Call is a radio show hosted by Dave Hunt and T.A. McMahon. They are non-Calvinists who hold to eternal security. Bob Hoekstra is a pastor with Calvary Chapel, and is also involved in prison ministries.
Here is the link to the audio resources: Resources on Calvinism
