how brave?

A young lad from Cincinatti overheard his father saying that his older brother needed a blood transfusion immediately. The youngster thought it over a while and though he wasn't quite sure what 'these blood transfusions' were, he asked his father, "Dad, can't I give Bud the blood transfusion?" The parents thought it over, and soon the mother took the boy to the clinic. Within fifteen minutes the nurse had removed the half pint of blood that was needed. The boy's jaw was set even though he was shuddering a bit. He raised his manly tear-dimmed eyes to his mother and quietly asked, "Mom, do I die now, like Jesus?" The mother almost fainted when it became clear to her how brave her boy had been. With a burst of love she drew his slightly protesting form to herself as she realized that he had thought that he was giving his life that his brother might live.
