How Do I Change the Main Content to show a Post instead of a Page

[rharejr]

I would like to have the middle section in the classic Executive theme show contents from a post instead of a page. Assuming the Post is assigned to category 4 What Do I need to change in the following home.php code to accomplish this:


<div class="hpmain">

<div class="hpmainleft">
<?php $recent = new WP_Query('page_id='.get_theme_mod('hp_main')); while($recent->have_posts()) : $recent->the_post();?>
<h2><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h2>
<?php the_content_limit(600, ""); ?>
<p><a rel="nofollow" class="more-link" href="<?php the_permalink() ?>"><?php _e("Read more", 'studiopress'); ?></a></p>
<?php endwhile; ?>
</div>
