Well I was wondering so I did a little looking around and found Dallas Jenkins her Grandson and either director or producer of the movie on Facebook and asked him that very question. His answer was
"Bonnie is my grandmother my dad's mother, who passed away late last year. she left a legacy of faith and was an incredible wife and mother, dedicated to Christ and sold out for the faith. No one ever questioned that she was acting within Gods Will. Dallas"
Hope that helps. It was an awesome movie at the right time in life when we all have those questions what if I could turn back time.
Other people asked questions on various topics, and are still waiting for answer. Would be great if you can take a sec and answer them
