I backed away from him slowly as I edged toward the exit. I can imagine people might want to "accept" Jesus just to get away from them.
I had something happen to me like what you described, and I also walked away. It was kinda freaky. But in this video, she looked as if she was really thinking about what he was saying. I think she's been finished with the Dubs for a while because she could never be "good enough". It seems he caught her at a time when she already felt "helpless". He seemed to know how to bring her out a bit. I also noticed he had a way to talk with her in a warmth tone and not like a "crazed, 'God loves you'" type way.
It will either do 2 things... it will push her to try to go back to the meetings. But then she'll feel like she has to admit to all her sins and she'll probably get disfellowshipped. Or she'll fall away even futher from the Borg and hopefully she can start looking into other options as well as being a BA.
