Look at Ps 23 for an example of the goodness of God towards sheep who are relatively stupid.
I have spent half an hour around sheep in my life, and that time was spent running away from a sheep which was trying its best to butt me.
Terrifying
So I am not in a real good position to relate to Ps 23.
But I do have a cat, so I relate to being a cat-owner. Cats are a bit like sheep, just harder to herd.
The point is that the cat owner/shepherd loves and cares for his animals because of his own goodness, not because of any intrinsic goodness on the animal's part.
My current cat has issues. He was obtained from an animal shelter - a rescue cat. I went to the shelter looking for a black and white cat. They did not have one. So less than ideal, I next looked for a black cat. R chose me, I did not choose him. He was the friendliest cat in a huge cage filled with cats.
I had brought a cage, but they insisted I take a stronger one. I wanted to pick him up, but they insisted on doing that.
On getting R home, I discovered why. He would not allow one to pick him up, and he was quite wild and may have escaped from my cage.
R obviously had not been properly socialised as a kitten. In retrospect, I think he was in a cage where they kept all the wilder cats. Like a maximum security prison.
The first few days he spent hiding away, even though he was trying to be friendly.
To this day he does not take being disrespected and has spilt a lot of my families blood by scratching us when we tease or move him against his will.
Also, he is not black, but in sunlight a dark browny-black.
And his front and back claws do not retract like normal cats. They permanently stick out, so you hear a tick-tick as he walks on a hard floor, just like one hears with dogs.
And his canines are longer than normal cats, giving him a sabre-toothed tiger look in that they protrude from his upper jaw.
He is very spoilt and will only eat fresh fish - no pellets.
This cat has very little going for him intrinsically and objectively.
But we love him. We have loved most of the bad personality traits out of him. The family are forever asking "Where is R?" if we have not seen him for a while. My family occasionally point out R's flaws, but I am blind to these.
Here then is my point. We love this cat possibly more because he had/has so many issues.
I think God loves us so much because we had/have so little going for us intrinsically.
And we all are rescue creatures. My cat has long forgotten what I saved him from, including possible death.
At night he will even poke his wet nose into my sleeping face and demand that I feed him. What a cheek.
But I get up, switch on the light, microwave him some frozen fish, and stagger back to bed.
The LORD truly is my Shepherd. He loves me in exactly the same way. And He loves all of you in exactly the same way.
