One of the congs around here had the following illustration given by the secretary doing the part:
"if you had three kids, and had saved up $10,000 each for them for any emergency health needs, and one kid got sick and needed an operation that totalled more that the $10,000 reserved for him, would you hesitate to use the money saved for the other two kids to help him? Thats what the GB is asking us all to do worldwide...to help others without as much money"
