Immortality

Question:
I'm becoming increasingly persuaded that our immortality and our reign a thousand years has been available for 2,000yrs if we'd pursued the Word of Faith that firmly.  Now, whether it's absolutely always been available or whether the Word's leaning towards disclosing more and more along those lines towards me BECAUSE it's His timing, I couldn't even begin to tell you.  I believe a New Testament person's lifespan has potentially always been a thousand years, but with the big emphasis upon martyrdom and all of the religious stuff that arose about heaven, it's not too hard to connect the dots on why either nobody in previous generations has ever entered into that, or because of persecution and avoiding publicity about it, they've simply kept a lid on it.  As far as partial preterism, or the idea that many of these prophesied events met their fulfillment in 70AD, in the years leading up to that, or within a century or two of that, I'm very acquainted with that view and do believe many New Testament passages have their fulfillment in that.  I'm tempted to believe the whole book of Revelation may perhaps have been fulfilled in the 1st century and that we need to look to 2Peter, the book of Zechariah, Hosea, and other passages of Scripture for what's yet to come to pass, but I'm still rethinking the book of Revelation and am not dogmatic about that yet without typing up a few more loose ends either for or against that view.  As far as the letters that begin the book of Revelation, I don't believe they necessarily reflect an overview of Church history to the time of the end because none of 'em reflect a fully matured Ephesians 4 Church.  To me, they're like the book of Acts or the issues dealt with in 1Corinthians to where it having fulfillment doesn't mean it's irrelevant to Christian doctrine.  None of those letters that begin Revelation show us a Romans 8 "manifestation of the sons of God" chapter of human history that we know from too many other things in the Scriptures must yet happen.
