I never thought of that before, either. My father and mother aren't here to think of me. Nor my brother. I did not make it to my grandma's funeral, but I heard that my dad, who officiated, said that every day my grandma prayed for all her kids, grandkids, and great grandkids. She had 8 children so that's a considerable amount of people!
I have 3 kids rather than 8, and 3 grandkids so far, but I certainly do think of and pray for them every day. I'm sure my husband does, too. Those thoughts and prayers are like an invisible, supernatural infrastructure. Kind of amazing.
I've read some discussions lately asking, what good is prayer? That invisible infrastructure is one benefit I never thought of before.
