All very good points. Thank you both. I've written and preached often over of the years on Calvinism, its error is and the harm it does. Many years ago when he was still alive and active, Sproul used to be on our local Christian radio at a time when I was driving. As he was talking I'd be talking back to the radio pointing out what scripture says ... and at time's yelling at the radio!

I certainly wouldn't recommend him. But that said, Ron is a mature Christian and a sound Bible teacher. I think for such a person there is material that Sproul (and other famous Calvinists such as D A. Carson, Jonathan Edwards, Charles Spurgeon, Andrew Murray, Martin Luther, and John Bunyan, to name only a few out of very many) gleaned from Scripture, that --when used judiciously-- could be useful in preparing lessons.
To remove the great expositors and theologians of history from our studies because they espoused Calvinism to one degree or another would be a mistake in my opinion. However I should have given my comments to Ron in a private message. It was not appropriate for me to post my comments publicly on a board where so many people, including visitors, read and might be led to believe that Calvinism is good doctrine. I apologize for that and regret posting publicly. I would delete my initial reply except that it has provoked some good and useful responses.
