If you have never visited or used www.biblicaltraining.org then I highly recommend you go and take a look now.
The specific reason for this post is to recommend the class called History of Philosophy and Christian Thought taught by Dr. Ron Nash. While I am not in complete agreement with everything Dr. Nash taught, he was a superb teacher. I listened to this seminary level course on my iPod the summer after I graduated and can still remember most of it with great clarity; no doubt due to the images Dr. Nash constantly used. If you do not have a good foundation in philosophy, this is the course for you. Even if you think you do have a good foundation in philosophy, this course will serve as a great review and will help you to remember an outline of the history of philosophy and key concepts. I hope you will register for free at Biblical Training and find it to be as great of a resource as I did.
