Display featured posts as the first?

How to display featured posts as the first in a standard loop?

I noticed the posts have class <li class = "jsFeatured">. I would like to always show up at the top of the list.

My code:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

<li <?php post_class(); ?>>
<?php the_title(); ?>
</li>

<?php endwhile; else : ?>
<li><?php _e( 'No posts' ); ?></li>
<?php endif; ?>

Thanks.
