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
?>
