In the sermon tonight we considered how it's not a lack of evidence or reason that people don't believe in Jesus. It's a matter of the heart. Here's a link to the article I mentioned. As Alan said after the service, a lot of decisions are not made in the head, but "in the gut".
Also worth a read on this topic is the Archbishop's latest column in Southern Cross magazine on why he believes in God. (Not yet on line but will appear here soon).
