Learning from the OT is a little different.
We often do not study the books of the Old Testament in an organized verse-by-verse way as we study New Testament books. OT books are much longer for one thing and not so easily managed in time-limited series. For another reason, they are narrative history books so frequently the lessons we learn are not in the short pithy statements we look for in NT letters but rather rise out of the over-all story line.
OT histories are the stories of real people interacting with God and each other.
The insights we uncover there grow out of the biographies of the people involved. We learn vicariously from their experiences. The story might be preserved for us as either a negative or a positive example. Looking for the bigger picture helps immensely. Knowing the cultural and historical context is usually essential too. And OT culture and history is less familiar to us that is the culture and times of the NT. But there are rich insights to be discovered if we take the time to dig.
This series focuses on insights from the first five books.
Most of my Bible study series have been written during weekly Bible study class series for a church group and then published on my website. By contrast, I am writing this series directly for my website. It will probably not see contributions as regularly but it will have a continuing lifespan as I discover new insights over time.
