But...

Presumably animals don't comprehend God. And they also don't comprehend sin. Maybe they go together. If our existence is only about survival, and not about right and wrong, then how can we know God?

I've had pets. We have a dog. Unquestionably they have cultural standards. There is social structure, and some sense of right and wrong, or at least acceptable and unacceptable. As a puppy, Toby would nip at us playfully, but never bite. He had some sort of judgement, or is it instinct?

Is knowledge of God and of sin merely a matter of intelligence, of ability to process information? Whatever it is, I think we can't know God without knowing sin.
