if you do not have a home.php in your template you can create it.
either
you can add this code in :-
single.php if you want to show posts on home page
or
page.php if you want to show pages on home page
it’s better to create a home.php file in your theme folder. The final code look like this,
<?php
get_header(); ?>
<div id="container">
<div id="content" role="main">
<?php // The Query
$args = array('post_type'=>'your_post_type',
'cat'=>'featured_posts',
'post_per_pages'=>'3',
'order'=>'ASC');
query_posts( $args );
// The Loop
while ( have_posts() ) : the_post(); ?>
<h2> <a href="<?php the_permalink(); ?>">
<?php the_title(); ?> </a></h2>
<div> the_content(); </div>
<?php endwhile;
// Reset Query
wp_reset_query(); ?>
</div><!-- #content -->
</div><!-- #container -->
<?php get_sidebar(); ?>
<?php get_footer(); ?>
