I have some of the same doubts you have, my fear is a neighbor showing up at the door with a staving child, so I do what the bible proscribes and try to put away an extra ten percent as a tithe. But as the head of my household my first duty after that to God is to my family. I can only be so responsible to others and will not place my family in danger to help the careless and the thoughless.
Agree. Our first duty is to family. It is not my responsibility to care for someone who didn’t prepare when all the signs were warning of danger.
Opening your door could turn your home into a superdome congregation and leave your family perhaps worse off.
When people are desperate your life is of no concern to them.
You hit upon the crux. Most folks do not want to even entertain those tough decisions. It is too painful to even comprehend, but it must be addressed.
The thing I notice is that women, who operate according to feelings and emotions moreso than men, are appalled when I proffer this exact concept; they cannot rap their brains around an actuality so horrible as this. My wife is the same way. I ran her through several scenarios similar to your scenario, then ran through them again with our (not yet in existance) children in the mix. All I succeeded in doing was to make her sad.
Finally! The correct answer to the question.
My last answer was "an extra 20-lb sack of rice doesn't cost much nor take much space", but I like yours better.
