Christian History Magazine
If you have logos, you ought to consider getting some of the issues on periods, groups, or individuals in church history.
Table Talk Magazine- RC Sproul
This is also on logos. The topics are very practical and address pertinent contemporary church issues.
Modern Reformation- Michael Horton
This publication can be read online, and the subscription cost is reasonable. The subscription also allows you to read back issues online, with many excellent topics and articles. I have a lot of these articles in the resource center, so I highly recommend this publication. The website also has a link to the White Horse Inn, which has an excellent podcast.
