LOL @ DonutZ!
WTWizard, I find it funny that your guilt involved those Christmas lights...yet this recent Christmas, your comments on the decorating were very in-depth lol. Funny how things change, isn't it?
As for jwfacts' topic, within myself I always thought that certain "sins" weren't necessary to confess. Sins where you weren't hurting anyone else, only yourself, could be brought to Jehovah himself (who I questioned the existance of anyway, but still cried and prayed to once in a great while just in case). Sins involving someone else...it depends on if they would be hurt by it or if they saw it as a sin at all.
For instance: My last JC, I confessed to the elders. At the time that I confessed, I felt it might hold me back spiritually because I was trying to strengthen myself. It took way too long to set up the JC and I ended up coming back here in the interim. So when the JC finally happened, I really didn't feel sorry or guilty. When I left at the end of it, I didn't feel any weight lifted or an improvement in my spirituality. I was just relieved it was FINALLY DONE after so many months of waiting!
So, no, my spirituality didn't improve...Actually, it didn't ANY time I had to be in a JC (I've had 3). I walked out of there feeling no different, thinking no differently than I did before. Just glad I got through them unscathed at the time.
