So I take it you don't mean it?

Not literally, no. 'Quite a lot' is stretching it a bit, come to think, but sometimes it seems appropriate.

You are telling me that you tell people that you want God to bless them but that you do not believe in God?

I don't, but the sweet little old lady giving me a cup of tea probably does.

Though you might call it cynical manipulative deception. Go on, if it makes you feel better :-)
