The human mind is still in the dark ages and will remain so till humans learn to eschew the made up concept of religion.
Religion still plays a major role in the lives of the majority of world population. People refuse to see reason and abandon logic . Belief in superstition and brainless faith in deities , made up attributes of thousands of gods still tickles their imagination and of course the dangling carrot of a grand after life.
Difficult to penetrate the mind with such mountains of garbage cluttering the brain.
For many of us it was easy because we all believed this was the truth. If not then there was no other that was true. From there it was but an open door to freedom once all of us discovered that both the Bible and the JW religion were just made up crap.
