I believe that if a non regular meeting attender shows up for at least the Memorial "celebration", it's a sign, that possibly, the person is saveable. Not all hope is lost for them.
I heard that last year, the rumour was that I was going to show up and sit with my mother....(of course, that never happened).
So, if you attended or if your family member or wayward friend showed up, they might have a chance for everlasting (earthly) life, after all!
