i have a fairly significant Logos library. I've been buying resources since the late 90's and i've prchased Logos 4 Gold, Logos 5 Platinum and Logos 6 & 7 Gold along with a significant number of other resources over the years. I'm not saying this to brag, but to lay the groundwork for what i'm preparing to say.
i'm not a pastor, but i've been teaching Adult CE classes (aka Adult Sunday School) for more than 30 years. I've been looking for a practical and useful way to make better use of my extensive library in preparation for teaching my weekly class.
what i've discovered is that adding the Lexham Bible Guides and the Exegetical Summaries to my library (by opening a new payment plan) has notched up the usefulness and access to my resources in a tremendous way. This month, The Lexham Bible Guides to Paul's Epistles are on sale for 30% off. Here are links to them. I also recommend the guides which are available on pre-pub right now.

As useful as these guides are, and they really are, there are two downsides: they are very pricey, and to be the most help, they require a significantly sized library.
in addition, besides these guides, the Exegetical Summaries Series is also an extremely helpful set of resources. They are most useful if you have a basic familiarity with greek and also a significant library. On the good side, they are far more economical than the Lexham Guides, though they focus not on exposition, but rather on exegesis. There is a full set avalable and also an additional 4 volume upgrade on pre-pub.

i recommend other users consider these two series as ways to make wading through and making use of your existing library easier and more powerful.
