Perhaps. I've toted a HCSB and then CSB Study Bible for quite a while, and still use them when I am tasked to teach, but lately I have just been carrying a slimmer Bible and breaking out my phone with my downloaded Faithlife Study Bible if I want dig into some background or context.
I'm wondering how a Study Bible based on a pastor's sermons instead of an academic's notes will affect my study. And if I can snag one for 25 bucks, I reckon it's go time.
This Bible would be a nice resource to have if the person editing it is expert at Spurgeon theology, and knew the appropriate message for the bookr under discussion.
I think they're great, personally. Maps, charts, timelines, illustrations, words studies, historical background, and sound theology. I prefer it's notes to the Faithlife notes, but both are pretty good. I need to borrow a copy of the new NIV with D.A. Carson's notes for a test drive, though.
