I cannot speak from direct knowledge of being DF'd as I have never been a JW, but when the chips are down, you find out who your real friends are. Jesus has ALWAYS been my friend.
There are a lot of views from people here that I agree with.
"I would never give a judicial committee the honor and dignity of my time and attention. They have no authority over me and cannot require me to do anything."
"what's more important to you, your relationship to God and Christ or your relationship with your family."
I think your letter is great. It tells from your heart what you really think. Short and to the point.
Along the lines of what I quoted I do not see myself giving anyone the time of effort to condemn me if I have in fact stopped believing what they tell me to.
I also know that in the end, the very end, we are going to be judged according to what we as individuals have done, not our family, not our friends not anyone else. I alone am responsible and will be judged according to what I have done.
