My favorite and, in my opinion, the absolute best Study Bible you can get is The Thompson Chain-Reference Bible (in NKJV of course). I have a TCR that I received as my first Fathers Day gift the year my daughter was born (2004). It is still in great condition and I use it regularly in my lesson and sermon preparations.
What makes the TCR such a good Study Bible is that it doesnt have commentary on the verses. Rather, it has topical listings that link verses together. It is a great tool in line with the popular saying, The Bible is its own best commentary. It also has a lot of good chart lessons and book overviews.
As always, great delivery time by Christianbook. In terms of craftsmanship, superb quality. I own a variety of study bibles, which are very helpful, however, this is truly a reference bible. God's most precious holy word comes first, and you can look up things in it for yourself. If you prefer to learn by looking things up for yourself, this bible is probably for you. Don't be mistaken, the added sections are fantastic, and I'd buy it for the archaelogical supplement alone, but this is a participatory bible, not for spoon feeding. And although the system is over a hundred years old, it's been updated nicely and good work never goes bad.
This is a very well made, easy to use, and understand copy of GODS WORD. You are able to search the meaning of a verse, or chapter of scripture, using scripture to enhance your understanding. That totally eliminates the input of a mans own personal interpitation of scripture, which could be incorrect. I'm not meaning to say not to use a study Bible, just remember that the notes in a study Bible are not scripture, they are mans interpitation.
