Listing posts from certain category

Dear Iconic team,

I have a page, where I want to list only posts from one category. I have created this modification:

	<?php if ( have_posts() ) : ?>

			<?php /* Start the Loop */ ?>
			<?php query_posts('cat=3'); ?>
			<?php while ( have_posts() ) : the_post(); ?>

				<?php get_template_part( 'content', get_post_format() ); ?>

But this prevents pagination from working. Is there a way to lists posts from one category and have pagination working?

Thank you for your reply.

Best regards,
Jan
