If you haven’t already visited two-age.org, you must click the link and visit. The site contains several articles and redemptive-historical sermons. They also have audio from the 2001 Kerux Conference on Biblical Theology. This is a wonderfully helpful site and I encourage you to bookmark it.
I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naïve. (Romans 16:17-18)
