David Lamb has a fine rant: I hate Study Bibles. Here’s the heart of it:
Study Bible comments are kind of like stuff on the internet. Sometimes the information is good, sometimes it’s junk. But at least when you go to the internet, you know you’re going to find some junk. You don’t expect to find junk in your Bible. At least you shouldn’t.
Some Study Bibles are relatively harmless, and even helpful at times. The notes are limited and just provide context and background that most typical Bible readers just don’t know.
The curse in Rev 21:18 is fairly explicit:
I warn everyone who hears the words of the prophecy of this scroll: If anyone adds anything to them, God will add to that person the plagues described in this scroll.
A charitable interpretation would be that the curse only applies to Revelation (“this scroll”) in which case I suppose a “study bible” with ZERO additions to Revelation escapes the curse. But friends your trusty NIV Study Bible is cursed with all the plagues described in Revelation!
