Dexter, My intent is not to communicate insults.
Yes I know, your intent is to be helpful, but proselytizing rarely comes across that way, particularly when you post citations from supposed authorities who clearly state that lack of faith in a particular dogma is due to some personal failure in the person who lacks it. It's not, it's just a different understanding of the world, and one at least as defensible as you find yours to be.
However, since you've conceded at least the possibility that you might be wrong, the obvious question is, what would it take to convince you you're wrong? And if I'm going to ask you that, you could reasonably ask me the same, so I'll answer it now. It would take a clearly and unequivocally miraculous event that admits of no other possible explanation but the supernatural. I can even give you an example. In moments of levity I'm likely to say something like, it'd take the appearance of a big pointing finger coming out of the clouds and a booming voice intoning, "You're WROOONNNGGG!" But I'll be a little more serious here.
My mother was a serious believer. She died 9 years ago, and one of the last conversations I had with her about this sort of thing involved her manifesting herself to me after her death. She was sure she could do it, she was convinced dad, who died a decade before she did, was doing it for her. I was equally sure she could not, so we worked out an arrangement to find out. She would have to appear before me and at least two other witnesses, to minimize the possibility of hallucination, we would all have to be sober and alert at the time, and all agree on the details of what we saw.
I probably don't need to tell you nothing remotely like that ever happened.
Here's another one that'd convince me. Get together as many people of like mind as yourself as you can and all of you pray seriously and earnestly for something as selfless and meaningful as you can think of like, for example, the remission of all childhood cancers, or the healing of all children crippled by multiple sclerosis or muscular dystrophy. If that works, I'll be convinced.
You know as well as I do what'll happen: nothing. And apropos of that, since the scriptures clearly say prayers will be answered, ask and it shall be given and all that, why would not that failure convince you you're wrong?
