I must not permit the evil capabilities of human nature to sour my faith in the tremendous good that is possible despite the frailty of that nature.

No man can see God in this life and live because His glory would annihilate our poor, weak human nature.

In each of us, two natures are at war – the good and the evil. All our lives the fight goes on between them, and one of them must conquer. But in our own hands lies the power to choose – what we want most to be we are.

I hope you haven't given up on the S.Q.'s of the world, Reynie. As you see, there are a great many sheep in wolves' clothing. If not for S.Q.'s good nature, we'd never have escaped.

as Schulz himself has pointed out, Snoopy is capable of being 'one of the meanest' members of the entire Peanuts cast ... he is lazy, he is a 'chow-hound' without parallel, he is bitingly sarcastic, he is frequently a coward, and he often becomes quite weary of being what he is basically -- a dog. He is, in other words, a fairly drawn caricature for what is probably the typical Christian.

Human nature is evil, and goodness is caused by intentional activity.
