A man had no kids “of his own,” but was in fact the guardian of countless hundreds of boys and girls.
These boys and girls had their own fathers, and they did individually more or less what a father does as his responsibility to their children; however successful they were…
...but this particular man gave to “his” kids what a normal father cannot give.
That thing was faith.
Whereas a father teaches a child what is right versus what is wrong, this father taught his children that both right and wrong are outside of your control.
The only thing in your control is what you take, not what is given.
