I must admit, I forget to pray for my deceased relatives. It's not that I don't believe it is important. And it's not because I don't believe it does any good. I just don't remember to do it.
So, I need reminders. Maybe you do as well. In my garden window, I have a tea cup. It is part of my grandmother's china collection, which I inherited. I keep this one tea cup where I can see it, and when I see it, I remember to pray.
Little reminders - a very good thing.
