Only Kirk could have the balls to challenge what is supposed to be the Almighty.
Kirk: What does God need with a starship?
McCoy: Jim, what are you doing?
Kirk: I'm asking a question.
"God": Who is this creature?
Kirk: Who am I? Don't you know? Aren't you God?
Sybok: He... has his doubts.
"God": You doubt me?
Kirk: I seek proof.
McCoy: Jim! You don't ask the Almighty for his ID!
"God": Then here is the proof you seek. *zaps Kirk with lightning, knocking him backwards*
Kirk: Why is God angry?
Sybok: Why? Why have you done this to my friend?
"God": He doubts me.
Spock: You have not answered his question. What does God need with a starship?
- Don't knock McCoy's reaction to 'God's' lashing out at Kirk.
"God": Do you doubt me?
McCoy: I doubt any god who inflicts pain for his own pleasure!
