An interesting perspective of "discourse analysis" has been applied by Dr. Runge for these commentaries. It is certainly useful to anyone trying to understand the thought and argument of Paul in this letter, but it works better in conjunction with a standard exegetical commentary, such as Gordon Fee's NICNT volume, than by itself. As a new type of commentary, Runge's volumes are useful and thought-provoking, but they should be used alongside traditional scholarship to provide the best balance of historically grounded exegesis and fresh analysis. Runge should be found on the shelf (or in the Logos Library) of any serious NT scholar that is interacting with the discourse of these NT books. Those with limited funds should acquire traditional commentaries before these specialized ones, but should come back to these if at all possible.

Logos 7 Silver is an excellent Base Pack, especially for those new to Logos. It provides a strong base for laymen, seminarians, and pastors. For those who can afford Gold, buy that instead. Gold's main advantage is the addition of numerous commentaries, mainly covering the New Testament (PNTC, NIGTC, BST, etc.). I can't justify Gold currently, but it is worth the money for those who are studying scripture more than I do.

See my review of the full set. All of the late Dr. Sproul's CQ primers are excellent introductions to theological topics. They are short and written primarily for laymen.

An excellent set of theological primers by the late Dr. RC Sproul. Written from a reformed, conservative presbyterian perspective, these books are short but useful, particularly as introductions to topics. Many of them were published as different books earlier in Sproul's career, but these new editions are quite good. Especially useful is the volume on Biblical Inerrancy, as it includes both the landmark Chicago Statement and Sproul's commentary on that statement.

While somewhat dated, this is an excellent resource for students of the Bible. It is relatively conservative, and it provides an interesting perspective from its historical context. I received it for free as part of a promotional several years ago, and I have often referred to it as a supplement to other Bible Dictionaries.

This is an excellent collection of primary sources for historians of the 19th Century in America. As a Civil War historian, the advantage of having them in Logos is that they are easily searchable. That being said, they are more difficult to use in terms of references, as these editions are not always clear about bibliographic information because they are transcripts instead of tagged scans. I sometimes have to find the passage I need in Logos and then use a PDF copy of the original to have an accurate citation. Still very useful for students of the American Civil War.
