It’s not an experiment I would recommend, but if any one of us committed for one year to: go back to all the meetings, lots of preaching, pray often, Bible/Watchtower reading, watch all the videos, really put sincere effort into it, and completely avoid any apostate or hostile media, and never say a word against the society and refuse to listen to anyone else with any remotely critical comments about the truth.
At the end of a year, if you do those things faithfully and without exception, you will probably end up believing JWs have the truth all over again. In fact, you will be confused about how you could ever have been fooled by apostate lies in the past!
Nah no way. It really depends why you left and why you stopped believing.
Jerusalem was not destroyed in 607 BCE and with that comes tumbling down the house of cards that this group are "chosen".
Going back a year and doing everything will not change that because they offer zero proof that Jerusalem was destroyed in 607 BCE.
