I recently mentioned the Founders Ministry, and I should have linked to a few more resources that could be useful.
The Founders publish their Journal quarterly-ish. It is focused on being useful for Reformed Baptist pastors and those interested in such things. Each issue has a theme and they range from Preaching, to the history of the Baptist Convention.
All in all, a good resource to be aware of. These guys are pastors in the trenches writing to the same. Here's their blog (I like the look of it).
