Looping one category

Oke so this is my code.
I used this code on my homepage to show the posts, as the template (Boldy) I’m working with doesn’t have a loop at the homepage.

What I want to do, and I’ve seen the same question come by but I can’t get it fixed, is show only one category named ‘blog’.

Can someone help me out on this?
Thanks in advance!

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

		<!-- Begin .postBox -->
		<div class="postItem">

				<h1><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h1>
				<div class="meta">
							<?php the_time('M j, Y') ?> &nbsp;&nbsp;//&nbsp;&nbsp; by <span class="author"><?php the_author_link(); ?></span> &nbsp;&nbsp;//&nbsp;&nbsp;  <?php the_category(', ') ?>  &nbsp;//&nbsp;  <?php comments_popup_link('No Comments', '1 Comment ', '% Comments'); ?>
						</div>
				<?php the_content(__('Read more >>')); ?> 

		</div>

		<!-- End .postBox -->

		<?php endwhile; ?>

	<?php else : ?>

		<p>Sorry, but there are no entries found to show.</p>

	<?php endif; ?>
