um Peter said a dog returned to his vomit, He was a dog. He never became a new creation. He did not return to being a dog (lose salvation and once again become lost, dead to Christ needing to be born again) he was already a dog. Who tried to act like a new creature (child of God.) but could not continue the acting, Why? A Dog returns to his vomit, why? A dog is a dog.
We are called lost sheep. My sheep know my voice etc.
Goats are not sheep or turn into sheep.
Dogs do not turn into sheep.
To then extend the analogy of dogs and sick to say the dog is not saved because
they are a dog shows the level of understanding and rigidity in thought.
It comes from the idea you are born again and cannot loose it.
But using the sheep analogy, before you are saved you are a sheep, you always
stay a sheep and can never not be sheep.
This does not mean you are a saved sheep or a lost sheep, you are just a sheep.
Some sheep are still rebellious and still never saved, and some sheep wonder in and
wonder out. Not difficult really.
