When I first left the J.W Org I decided I needed to research properly, looking only for facts and evidence that would withstand any scrutiny and any attack, only "truth" of that calibre would suffice.
I started in the reverse order to the one they give in that W.T. number one was the Org, was it " the truth" ? Answer NO !
Number 2 was " The Bible, is it god's word ? " Answer NO!
Number 3 was " Is there a god ?" simple answer NO ! ( certainly all the gods man has made up, even new boy on the block Jehovah, do not exist).
The Org's 3 reasons were demolished completely by proper research that established the Truth of these matters.
A bit of advice to folks who have not done this, start with my Number 3, once you have established that no god invented by man exists, the other things do not matter, apart from perhaps getting rid of the feelings and fears, like Armageddon etc, that the Org embedded in us.
To really " use your power of reason" as the WT says , and use it properly, is to come to the same conclusions as me. If you do not wish to fully use your power of reason, do not want to think rationally, do not want to accept Truth, you remain entrapped in Delusional Belief, a sorry Mental Condition ( Illness).
