Question 8

Is it so terribly inconceivable to comprehend God with one's senses? Why does he hide in a cloud of half-promises and unseen miracles? How can we believe in the faithful when we lack faith? What will happen to us who want to believe, but can not? What about those who neither want to nor can believe? Why can't I kill God in me? Why does He live on in me in a humiliating way - despite my wanting to evict Him from my heart? Why is He, despite all, a mocking reality I can't be rid of?

or, from a different film:

Especially important is the warning to avoid conversations with the demon. We may ask what is relevant but anything beyond that is dangerous. He is a liar. The demon is a liar. He will lie to confuse us. But he will also mix lies with the truth to attack us. The attack is psychological, Damien, and powerful. So don't listen to him. Remember that - do not listen.

Actor, as two different characters, from two unrelated films in 1957 and 1973, respectively.
