I believe that God can restore people and He does. That's one of His jobs! If she or any other person turned to Him, repented, turned their lives around, then all this is possible. There IS a God factor, but I don't know if that's what happened in her case. If she's a lesbian, she certainly isn't following His principles. But, I won't judge her because I don't know all the facts.
I believe it doesn't happen as often and dramatically as one would hope. Therefore, I am still skeptical. And as for judging, no one ever knows all the facts, not even jurors in trials. One can only judge what one can see.
