Why does my loop only render one blog post?

Hi guys! I need some WordPress help again. I have 6 blog posts but my loop only renders one of them.

Note: this is a second loop. I have another loop before this that runs as I want.

<?php
      if ( have_posts() ) : the_post();
      ?>
        <div id="orange" <?php post_class() ?>>
          <h2>
            <a href="<?php the_permalink() ?>">
              <?php the_title(); ?>
            </a>
          </h2>
          <?php the_content(''); ?>
        </div>
      <?php endif; wp_reset_postdata(); ?>
