Great Bible study tool! I enjoyed this one more than I have a lot of other Bible study books. I really enjoyed the format, and how commentary and context was given for each few verses, instead of long overviews of the whole chapter. I found the majority of the content in alignment with the other Bible study tools I'm currently using.
I would highly encourage this author to find a good proofreader whose first language is English. It was clear that English is the authors second language, and there were a few insights or comments that would have been offensive to me had I not taken this information into consideration. There were also sentences that should have been worded differently, that again, could have easily been edited by a proofreader.
Overall, I was pretty delighted to have come across this Bible study tool, and look forward to continuing with the other books in the series. If you get easily overwhelmed with busy and complex Bible study tools, I would highly recommend this one. You'll get depth, without it feeling overwhelming.
