The hardest thing? Deciding to do it.
But after realizing that Jehovah is not God, it was lots easier. Who wants to worship a phoney-baloney God? Who wants to regard an organization of men who teach this phoney-baloney God?
And being a believer in evolution made it easier. Not only have we physically evolved, we've evolved spiritually as well, our spiritual awareness has evolved and with it our concept of God has evolved. Now we can worship a Father image, the one taught by the master.
And we DO NOT have to give up the desire for life. We have not evolved throughout the ages only to end up here at the unchangeable NOW. We leave this life and continue to evolve, to evolve into beings who are less material and more spiritual with each step until in the far distant future we have evolved into pure spirit beings. Evolution is forever - and so is life. And we are free beings, as Jesus said "the truth shall set you free" and so we are free of the GB, the WTBTS, the phoney posturing, the phoney "field service" the slaving away doing things we'd rather not so that the boys in Brooklyn can count the money. Free at last. Free forever.
