Well I just read in several chapters of the Geneva Bible and it reads almost identical to the KJV. NKJV is just a modern English interpretation of KJV. Also you can't get older than the Textus Receptus, etc....You'll need to find yourself a Geneva Bible, or older, rather than all these variants of the Scotfield Bible, and then start examining the verses that give you your world view.
That's where some HUGE differences crop up regarding Israel. In that the differentiation is not of Israel but that of the bloodline of Abraham. Which gets uncomfortable for a lot of folks because that would also mean these same beliefs about blessing these people would necessarily also extend to Arabs.
So the Biblical principles of Christianity supporting Israel is still there.
Have you personally read the entire Geneva Bible or any Bible translations from Genesis-Revelation? Can you read Greek? Have you read the Textus Receptus? Or Septuagint?
