One or two landing pages?

I want to advertise my book about Bible.

For keywords like "Bible contradictions" there should appear landing page with a copy of the chapter of my book which lists five contradictions in Christian teaching, to intrigue the reader to buy my book in order to read how these apparent contradictions are resolved.

Should I have a separate landing page for less generic search queries such a "Bible"? Or should I direct ALL Google AdWords traffic to the page with the chapter about...

One or two landing pages?
