Answer:
So basically, the moral is that everyone dies in this world, so there's no point in crying over the dead.....
In this story the Lord sends the woman to find mustard seeds from a house where nobody has died however, she cannot coz a house like that doesn't exist, everyone has lost at least one person from their lives, so there was no house that had every single member of the family alive.This displays the fact that at one point in life we can loose someone, but we need to remember that the way life is.
