Inerrancy

I have been thinking about inerrancy and how to simply define it. So often definitions get caught up in the technicalities of what constituties an error etc. I wonder if this starts from the wrong place - and rather we should start more simply - with God himself. So, can we define inerrancy as follows:

The Bible (as originally given - there is a post in that on its own!) says exactly what God wants it to say.

What do you think?
