Although some cultures have trained domesticated dogs to become expensive family pets which enjoy the run of the house, they are still dogs.  All dogs, whatever their breed and however cute, affectionate or obedient, are derived from the, now extinct, Grey Wolf.  Under the right conditions even home-bred dogs will start to show some wolf-like characteristics, especially when they are very hungry.  But all over the world, most dogs have no human kindness or domestic home: they will eat whatever they can find.

This verse is well known and even quoted by people outside the Christian faith. It has a 'ring of rightness' about it.

It would be nice to think that everybody who claims to speak for God is one of His messengers. But that is not true. There are true prophets and false prophets.

This well-known story is based on the reality of extreme weather which continues to devastate many parts of the world.
