Hi Midnight, sorry to say but I really do feel sorry for you. You said: After much research and prayer.
Funny as many on here and other forums also say After much research and prayer and decided to stay away from the WT. Or they become Catholic, Protestant or Hindu, or Muslim or even Buddhist. Go figure, same attitude, many different outcomes......
despite mistakes and errors
And you refer to the promised land. Do you know who was not allowed to get into the promised land? Was it because of the one error he made? Compare that to the number of errors of the WBTS organisation. Again, there are more reason to believe JW's will not enter the promised land than that they would (I mean with JW's not the individual but a collective group of members of the WBTS).
I understand that one feels comfortable in the organisation. Most of them have their family there, their friends and other relatives. And some congregations are quite nice (friendly elders, nice people, various social activities, relaxed attitude etc). And if that is the driver to join or stay, I can appreciate that.
Anyway, fortunately you live apparently in a country where you can make your choice of religion freely. And I wish you all the best.
