I’m not sure I understand your request, so I’ll make an assumption here. My assumption is that what you want to do is include a single recent post on a static page. So, in your page template the most efficient way to do that would probably be with a WP_Query object.
I use this in a particular area on my site.
<?php
$recentBlog = new WP_Query();
$recentBlog->query('showposts=1');
if ($recentBlog->have_posts()) : while($recentBlog->have_posts()) : $recentBlog->the_post();
?>
<h2><?php the_title(); ?></h2>
<p><?php the_content_rss('…', 0, '', 50, 0); ?></p>
<a href="<?php the_permalink('Find Out More…'); ?>">Read More…</a>
<?php endwhile ?>
<?php else : ?>
<h2>Temporary Filler Box</h2>
<p>This is temporary filler, because the content that's supposed to go here isn't here.</p>
<p>How terribly lazy. Come back soon, and maybe there will be something.</p>
<?php endif ?>
That returns the single most recent post from the blog.
Just include something like that on the page where you want the recent post to be displayed.
