If one was to answer the question posed by JaKa, "....which of you have done charity without consideration of your personal benefit", then I'd guess JaKa would say that the recounting of it would no longer qualify it as a charitable act done "without consideration of your personal benefit".
The wife of a friend gave a kidney to a woman she didn't know. She heard of this woman's plight through a mutual friend and decided to make the donation. Barb, the donor, is not a religious person, accepted no money, and shunned any fanfare. I don't know her 'motive', but what's left?
Shelda, the recipient, is immensely greatful.
A young cousin of mine needed a bone marrow transplant and hundreds of people came forward to be tested. What's their motivation? Are all of them guilty of doing it for some sort of personal benefit? I don't believe so.
Some thirty years ago a friend of mine living in Toronto was also faced with needing a bone marrow transplant for leukemia. Turned out that the only 'match' found was from his overweight brother. He forced himself into losing the massive amount (nearly 100 pounds) of weight that the doctor's required before they'd take his marrow. What'd he do that for? Simple - love for his brother. Costas is now the longest bone marrow recipient in that country. His brother, Marco, has never reminded him of the 'gift'.
