I've been listening to an Introduction to Calvinism on the Theology Unplugged Podcast from Credo House Ministries, and I highly recommend it to anyone who would like to learn more about Calvinism. Michael Patton, Tim Kimberley, and Sam Storms do an excellent job of presenting the Doctrines of Grace with honesty and clarity. While they are all three are committed Calvinists, they do try to portray the other side fairly and respectfully. They present the evidence for Calvinism, as well as those passages that aren't as easily reconciled. These passages must be held with some tension, and as a credit to them, they openly admit these areas rather than simply glossing over them.
There are 15 Podcast in this series. Yeah, I know. Five points in fifteen episodes. Don't let the length scare you. They are all very enjoyable to listen to and very informative.
