Never been a JW, just your regular non-denominational Christian my whole life. I personally think, from numerous Bible readings, that all that's really required for guaranteed salvation is to accept and confess Christ as savior and to repent of your sins. I also feel that any good people who had no faith in God or Christ will also be saved on the day of judgment. Maybe I'm too starry eyed or naive, but I feel that only genuinely bad people will be in hell.
I honestly feel that it doesn't matter what denomination you are, either. I used to, but when I became a more liberal-type Christian and REALLY read the Bible, I changed my mind. And I try not to associate with any church that says "so and so is going straight to hell!" Since you're judged with the same judgment that you put toward others, does that mean that those pastors are all going straight to hell?
