>A generous man will prosper, he who refreshes others will himself be refreshed (Proverbs 11:25).
I don’t think this means that if we give a hundred dollars to charity, we’ll win the lottery. I don’t even think it means that if we give a man our coat, we won’t be cold. If we only have one coat, we can share it. By wrapping it around someone else, we get the benefit from their body heat. Thereby, we are both the warmer for the sharing.
