Reference content from a page on the front page

This might sound confusing, but I don’t know how else to explain it. Currently, my site references my posts and displays excerpts of them on the front page. What I want it to do instead is reference the material from a single page and display it in its entirety on the front page. Is there a way to do this?

My only other option would be to hard code whatever I want displayed into index.php, which I want to avoid at all costs (in case clients should want to modify the front page).

Any help would be much appreciated.

Thanks.
