Well, I listened to the podcast on the commute to and from my daughters’ school. It is 45 minutes long and it was an interesting discussion (remember, I’m in seminary and find theology interesting). I think they cover a subject that is little understood in the church, the ordinary means of grace. I recommend listening to it and then going here to post a comment or question. This can be a wonderful resource, so you should take advantage of it. Understanding the means of grace will help you understand what is happening during the worship service.
