Of interest to readers of hebel will be the contribution by Michael Spence. Dr Spence in the Vice Chancellor of Sydney University. He is also an ordained Anglican minister. I heard Dr Spence on Saturday night, and he said that his Hope 2010 speech was an opportunity for him to give 'account of the hope that is in you' (cf. 1 Peter 3.15).
You can listen to Dr Spence's address here.
