C.S. Lewis, a world-renowned Christian theologian, writer and professor, leads a passionless life until he meets a spirited poet from the U.S.

Jack: Why love, if losing hurts so much? I have no answers anymore: only the life I have lived. Twice in that life I've been given the choice: as a boy and as a man. The boy chose safety, the man chooses suffering. The pain now is part of the happiness then. That's the deal.
Harry: [Jack makes his first public appearance after Joy's death] Well done, Jack. Life must go on.
Jack: I don't know whether it must, Harry, but it certainly does.
Joy Gresham: We can't have the happiness of yesterday without the pain of today. That's the deal.
Harry: Christopher can scoff, Jack, but I know how hard you've been praying; and now God is answering your prayers.
C. S. Lewis: That's not why I pray, Harry. I pray because I can't help myself. I pray because I'm helpless. I pray because the need flows out of me all the time, waking and sleeping. It doesn't change God, it changes me.
Harry: But she's not...
C. S. Lewis: Not my wife. No, how could she be? I'd have to love her, wouldn't I? She'd have to be more important to me than anything in the World. I'd have to be suffering the torments of the damned. The thought of losing her...
Harry: I'm so sorry, Jack. I didn't know.
C. S. Lewis: Neither did I, Harry.
Joy: The pain then is part of the happiness now. That's the deal.
Joy: Jack, don't you sometimes just bust to share the joke? Here's your friends thinking we're unmarried and up to all sorts of wickedness, when all along we're married and up to nothing at all.
C. S. Lewis: Pain is God's megaphone to rouse a deaf world.
Douglas Gresham: [Reading Jack's inscription from his Narnia book] The magic never ends.
Joy: Well, if it does, sue him.
Joy: Back where I come from, there's this quaint old custom. When a guy makes up his mind to marry a girl, he asks her. It's called proposing. Did I miss it?
Jack: Will you marry this foolish, frightened old man... who needs you more than he can bear to say... who loves you, even though he hardly knows how?
C.S. Lewis: Have you got any cranberry sauce, Mrs. Young?
Mrs. Young: Cranberry sauce, what's that?
C.S. Lewis: Well, it's a sauce made from... cranberries.
Mrs. Young: Well, you find me some cranberries, Mr. Lewis, and I'll sauce them.
Jack: I love you, Joy. I love you so much. You made me so happy. I didn't know I could be so happy.
C.S. Lewis: He comes; he sleeps; he goes. So the plot thickens.
Joy Gresham: Are you TRYING to be offensive, or merely stupid?
[mourning Joy's passing]
Douglas Gresham: [sobbing] I sure would like to see her again.
C. S. Lewis: [also sobbing] Me too.
