1.) As I understand it, Charles Taze Russell was of the opinion that the natural Jews were going to be restored to Israel and that his preaching was centered with that in mind (especially in his later years). It sounds strange considering what WT is today.
2.) Remember, "The Bible" is just the name given to the cover wrapped around 66-72 (depending on who's counting) books. Think of it this way: you could take a number of books on any topic, say math or gardening, arrange them in some arbitrary order then publish them under one cover, kind of a "best of" volume. That's the idea behind "Bible". Now "Scripture"; that's a different thing altogether! When you read "...all scripture is inspired by God..." don't think of it as meaning each and every line of "The Bible"; think of it more as the stuff in Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. The other book in what some call the "Old Testament" aren't even on par with the God-inspired stuff in the first five, and the stuff in the "New Testament" is more like "what we thought and did once we got interested in the "scriptures"", a journal of how people took what they'd read in "scripture" and applied it. That's a *very* loose explanation; I hope it serves to highlight the difference between "Bible" and "Scripture". The two concepts are not interchangeable.
3.) Oh, rats! I had a third point in mind but it's taken me so long to write the first two that I forgot what it was! If it comes to me in the time allotted for editing a post I'll come back and add it in. If not, well...you'll know it when you read these lines!
