Inserting post content into pages when using custom taxonomies

That code never outputs anything to the page:

<?php if(has_term('ART', 'product_relevance')):
   $my_post = get_post(927);
   if(isset($my_post->post_content)): ?>
      <div class="row">
         <div class="notification col-lg-9 order-1">
            <?php echo $my_post->post_content; ?>
         </div>
      </div>
   <?php endif; ?>
<?php endif; ?>

Untested, but in essence you need to do something with the post content.
