The ESV Study Bible is available online for free trial during this month of March. It contains over 200 color maps, 20,000 notes, 200 charts and 40 drawings of such things as the known buildings of the city of Corinth in Paul's day. The general editor for the New Testament section, Dr. Thomas Schreiner, has been a guest speaker at my church a number of times. He strikes me as a humble and godly scholar.
No, I have no financial interest in the book. I won't get any money from your click-through, even if you buy the book.
As with any study Bible, think of the notes as helpful comments from a godly but imperfect friend.
