I find his comment a bit puzzling. If Inglis thinks that Jesus requires him to give his life for others, then the world is chock-full of opportunities to do what's required of him. What's he waiting for? Reminds me of a dialogue from I Claudius:
Lentulus: (kissing Caligula's hand) Your recovery is a miracle!
Caligula: But you prayed for it, Lentulus.
Lentulus: Oh, night and day! But prayers are not always heard.
Caligula: But yours were special, so I understand. You offered your life to the gods in place of mine. That was extremely noble!
Lentulus: It's true, I did.
Caligula: And what are you going to do about it?
Lentulus: Do about it? What do you mean?
Caligula: Well, I'm still here, and so are you. But we oughtn't both be here. Should we not give the gods the things we promise them? You're in danger of the crime of perjury, Lentulus. Think about it. But not too long–gods won't wait forever, that I can assure you only too well.
