WordPress unexpected end of file

I have this custom php in my index.php. I’m trying to do a custom theme and I’m getting an “Parse error: syntax error, unexpected end of file”

I can’t spot my error! Any help appreciated!

<?php get_header(); ?>

<div class="container">
    <div class="main-content">
      <?php
      query_posts('posts_per_page=6&offset=1');
      if ( have_posts() ) : while ( have_posts() ) : the_post();
      ?>
        <div <?php post_class() ?>>
          <h2>
            <a href="<?php the_permalink() ?>">
              <?php the_title(); ?>
            </a>
          </h2>
          <?php the_content(''); ?>
        </div>    

      <?php if (have_posts()) : ?>
      <?php while (have_posts()) : the_post(); ?>
        <div <?php post_class() ?>>
          <h2>
            <a href="<?php the_permalink() ?>">
              <?php the_title(); ?>
            </a>
          </h2>
          <?php the_content(''); ?>
        </div>
      <?php endwhile; ?>
      <?php endif; ?>
    </div>
    <div class="sidebar">
  </div>
</div>
