Importing page styling into a different Wordpress template

Importing page styling into a different Wordpress template

I'm playing around with a wordpress theme from the ground up and want to
pull in a particular page's content into the home page along with any
styling I made in the editor (line breaks, color changes, bolding, etc.).
As of right now, it just pulls the text with no line breaks or anything
else. Here's the code I'm using to pull in the page:
<?php
$home_page_post_id = 15;
$home_page_post = get_post( $home_page_post_id, ARRAY_A );
$content_home = $home_page_post['post_content'];
echo $content_home;
?>
What in the world am I missing? Thanks so much!
