As for saving lives and owing lives: why would anyone employ a cleaner?
If it is to make their life easier, it may not be saving it in the dramatic sense, but if it improves your life, makes you happier, able to face life with a bit more confidence, there isn't much difference.
It is indeed, literally true. I try to live as Christ taught. He said ''If you are hoarding things, or have things and you see your brother/friend in need, give it to them''. He also said, when telling the story of the widow's might, ''what profit is there in giving when you have plenty?''
If you are attempting to make me, a disabled person, into someone without much sense and vulnerable, please don't try. 'been there done that' and on the receiving end of worse. People do, unfortunately label us with more vulnerability than common sense. It is a cross disabled people bear, because despite there being discriminatory laws, people still think they have the right to insult.
You are turning a comment I made on the OP into something I never invited.
If you cannot understand how ensuring that someone you rely on is content in their work, I am sorry. Insulting me may salve a conscience, but why would you want to be so nasty, just because you cannot understand how to treat employees?
