Why would you take the $20,000 allocated to the other two children, or even the $10,000 from the sick child if you had $1,000,000 in your own bank account?
Besides, it is not a matter of the organization having set aside money to give to each congregation (child), it is the congregations (children) that give to the parent.
The parent (if he hadn't been wise enough to have health insurance) would more than likely sell some of his properties in order to meet the debt. The Stanley Theatre alone would be a good example. But as far as the org. goes, they aren't talking about lifesaving necessities, rather just desireable 'wants' as opposed to 'needs'.
