[php] How do I display a wordpress page content?

I know this is really simple but it just isn't coming to me for some reason and google isn't helping me today.

I want to output the pages content, how do I do that?

I thought it was this:

<?php echo the_content(); ?>

For people that don't like horrible looking code with php tags blasted everywhere...

<?php
if (have_posts()):
  while (have_posts()) : the_post();
    the_content();
  endwhile;
else:
  echo '<p>Sorry, no posts matched your criteria.</p>';
endif;
?>

You can achieve this by adding this simple php code block

<?php if ( have_posts() ) : while ( have_posts() ) : the_post();
      the_content();
      endwhile; else: ?>
      <p>!Sorry no posts here</p>
<?php endif; ?>

Page content can be displayed easily and perfectly this way:

<?php if(have_posts()) : ?>
    <?php while(have_posts())  : the_post(); ?>
      <h2><?php the_title(); ?></h2>                        
      <?php the_content(); ?>          
      <?php comments_template( '', true ); ?> 
    <?php endwhile; ?>                   
      <?php else : ?>                       
        <h3><?php _e('404 Error&#58; Not Found'); ?></h3>
<?php endif; ?>         

Note:

In terms of displaying content - i) comments_template() function is an optional use if you need to enable commenting with different functionality.

ii) _e() function is also optional but more meaningful & effective than just showing text through <p>. while preferred stylized 404.php can be created to be redirected.

Just put this code in your content div

<?php
// TO SHOW THE PAGE CONTENTS
    while ( have_posts() ) : the_post(); ?> <!--Because the_content() works only inside a WP Loop -->
        <div class="entry-content-page">
            <?php the_content(); ?> <!-- Page Content -->
        </div><!-- .entry-content-page -->

    <?php
endwhile; //resetting the page loop
wp_reset_query(); //resetting the page query
?>

This is more concise:

<?php echo get_post_field('post_content', $post->ID); ?>

and this even more:

<?= get_post_field('post_content', $post->ID) ?>

@Sydney Try putting wp_reset_query() before you call the loop. This will display the content of your page.

<?php
    wp_reset_query(); // necessary to reset query
    while ( have_posts() ) : the_post();
        the_content();
    endwhile; // End of the loop.
?>

EDIT: Try this if you have some other loops that you previously ran. Place wp_reset_query(); where you find it most suitable, but before you call this loop.
