It seems to me that this "spiritual materialism" and the inability to see beyond the physical and fleshly world draw many to become and remain Witnesses.
Well, the WTS did bring out a principal text book called "You Can Live Forever In Paradise"! So who's to blame for inculcating a materialistic mentality instead of a real spirituality?
When the thoughts of a paradise earth, with a home for everyone, animals and humans at peace, all nationalities at peace, with plenty of food and good health for all, are inculcated in you from the first meeting with a Witness at your doorstep, or from babyhood for those raised as Witnesses, why else would you think or dare to dream of anything more?
And if you're told that only 144,000 are going to heaven, and too bad, you're not one of them because you were born too late in the 20th Century, you've got no reason to meditate on spiritual issues, as opposed to fleshly ones. You're taught that you're not going to die, that this life you've got is going to take you through the big A, so why complicate yourself on things of a heavenly nature? If it's not for you, and you're basically forbidden to even contempate it, then why not focus on a beautiful big house, with a family and lots of pretty gardens and never a thought of getting sick nor dying!
Hmm... might go to the Sunday meeting tomorrow....
