Someone once said, Responsibility is when Opportunity and Ability come together.
If someone's needs exceed my entire gross worth (let alone net worth) I do not have the ability to do more than contribute a portion. I may be responsible for that portion, but that does not give me the right to take the property of a Rockefeller or a Bezos without their consent to help this other person. When my ability is completely exhausted I have no further responsibility.
Also if I do not have the opportunity, I am not responsible. Now some people who are present at the time of a crisis may claim to not have the opportunity but I am referring to those situations in which for one reason or another the opportunity to help someone does not exist.
When my wife was dying I lacked the ability to keep her alive. Nor was the hospital to which I took her able to keep her alive. They entubated her and put her in a helicopter but when she arrived at the hospital to which she was flown, she was no longer responsive.
Neither I nor the local hospital had the ability. The hospital to which she was flown did not have the opportunity.
God can do what man can not do.
I'm not sure who you are thinking of when you suggest that somebody, somewhere offered prayers without doing anything, I'm sure that this sometimes occurs — BUT, we were talking about whether a memorial is more potent than prayer. Koons made a memorial then @lidja posted a message on Cake with the title Better than "thoughts and prayers?"
I am aware that someone used that phrase this year or last but who it was and under what circumstances I don't remember —
I was writing on the question of whether prayer is more potent than a memorial. I wrote about two kinds of people - those who are Atheists and those who believe that God is a caring God. I acknowledged that to an Atheist, prayers are empty and void; but I also pointed out that those of us who believe in a caring God believe that prayer is more potent than any symbolic gesture.
How this leads to a discussion of those who will not help when they have both ability and opportunity, I do not know.
