Here is the link to an apologetics and outreach course by Jerram Barrs at Covenant Seminary. It looks like the accompanying book is "The Heart of Evangelism" by Barrs. I'm going to download this to my Ipod and listen to it on Sabbatical this May. The lecture titles look very promising. It sure looks like this is not just your standard apologetics stuff (teleological argument for the existence of God, presuppositionalism vs. evidentialism, etc) It looks instead to be very oriented toward engaging the world with the Faith. Check it out.
