You will love this new book by Seth Postell, Eitan Barr, and Erez Soref. They teach that we can not understand the sacrifice of Jesus, atonement, and New Testament theology unless we have a good grasp of the message of the Hebrew Scriptures. They also show how Jesus is the goal of Torah. If you struggle getting the big concepts of the Old Testament, this book helps you to connect some dots.
For further reading, check out the works of Lois Tverberg. Here are a few books that I like that help me to understand the context of the Bible:
"Sitting at the Feet of Rabbi Jesus"
"Walking in the Dust of Rabbi Jesus"
"Reading the Bible with Rabbi Jesus"
