Dispensationalism

So I finished 2 messages on dispensationalism at my church. My personal opinion is that the first message was pretty good, but the second one was a bit more esoteric. Maybe I should have stuck with a single message, but really to have a good understanding of this doctrine I needed the second message to explain the history, some of the objections, and to spend a couple of minutes discussing (in I hope a respectful way) Covenant Theology and issues like Ultradispensationalism. But as I said the first message went quite well.
