Hi I'm also very new to this site, I'm now an ex JW, I have to agree with you that holding on to resentment can harm you on the inside.
But to have resentment is to show anger and anger may be unjustified or justified, was not Jesus justified when he drove out those who were defiling God's temple and overturned the tables.
Sometimes anger can be allayed or satisfied only when justice is fully carried out. Ecc 3:1-8 "for everything there is an appointed time, and even a time for every affair under the heavens"........."a time to love and a time to hate"
I don't hate the JW'S my parents are still in the organization, but I do feel justified at feeling anger towords the GB for the harm it has brought to the faithfull followers of them. ( the teaching on not having blood one example)
I have read hundreds of threads on here and would like to thank all who have clearly spent a lot of time and effort posting some of their researched material, it has actualy stoped me from turning to alcohol and a box of pills.
I have read many times over and over again how people have been spirituality and physically abused by the organization and I for one am glad for this site so that these people can vent their feelings and start to heal and know they are not alone meens so much to anyone.
