Magnum- Good topic. It is awful that you have had so much wasted time in the ORG, but do not let your heart be sad. You figured it out. You were deceived because you had no choice. You're parents and grandparents were JWs. You were raised in it and never had a shot at truth.
My brother is like your grandfather, his kids are like your mother and his grandkids are like you. He will [has] bring them up believing that they are more special than everyone else, but will get very upset when confronted with facts about reality. Really? You wont die? Millions living now will never die?
What to do now is a bigger question. Live a life well lived. Enjoy the wonder of creation and thank God for the obvious things like family, friends, health, mobility and life. Also thank God for the bad things and troubles. How would you know to be thankful for the good things if you didn't have bad things to contrast the good things against? The WTS will go on, but without you....and that's good
The Truth Will Set You Free
