According to the account in Bible (if it was translated correctly) the Israelites (if they existed) made it to the promised land but it didn't mean anything for them long term. What happened to them after they entered the promised land and where are they now?
There is nothing that I know of in the Bible that actually says there would literally be modern day Israelites and if there is, there is no proof that JW's are the ones to fill that role. JW's also insinuate themselves into the role of the "faithful and discrete slave class" even though there was no indication that there would be a Slave "class" and it would be literal and that role (if there was one) would be filled by a modern day religious group and JW's would be that group.
At any rate, unlike a lot of us who were raised as JW's and were forbidden to look at outside information before baptism, you have at least dared to go against the stern directives that we abided by and can now make an choice based on what you've learned so far.
As someone who watched his father die a horrible death due to the blood issue, my advice is for you to be sure you thoroughly understand the scriptures that JW's use to support that stand as well as all of the surrounding verses and know the context in which they were written. Ask yourself why the scriptures show that those who went against the early laws regarding animals and blood, were only considered unclean until sundown and why no one had to die over "misuse of blood" yet today JW's are expected to die and let their kids die over this.
Also, do not to putt all your eggs in one basket in terms of planning your future because so far, everyone who has ever lived, whether or not they believed in a "promised land", has grown old and died. Chances are pretty high that you'll need to count on growing old and having the resources to take care of yourself when you are.
I'm in my Late 50's and am ready to retire in the next few months, with a pension and additional income. Many of my contemporaries counted on being in the "promised land" long ago and viewed it as a lack of faith to prepare for the future. Some of the old pioneers and circuit overseers I know are in their late 70's, living in mobile homes, or rental units, driving school bus or have several part time jobs and are struggling. Back in the 1970's they thought the end was finally on the horizon and disregarded the evidence that the elderly folks who came before them and were dying one by one and had been duped into believing the end would come in their day as well. I never bought into this trend and from what I read in the literature and heard from the platform was made to feel unfaithful for planning for a future in this system.
Each JW generation that comes along convinces themselves (via repetition at assembles, meetings, and in the literature) that despite all the evidence before them, that somehow they will be the ones who won't have to grow old and die. It's human nature and it's the only way many of them can cope,
