php href hyperlink to specific post - php

Question

on my site, i have 4 "Program" names that link to the same page.
however instead, i want each program to link to a SPECIFIC POST.
BUT, in my php code, the names are and link are all controlled by one thing...this:
<h3 class="sub-title"> <?php the_title(); ?></h3>
if I change that href="http://questtkd.com/programs/" to href="?php the_post(); ?" will it break my site? or will that do the trick?
how do I change that href so that each sub-title will go to a specific post?
here is the code:
<?php
/**
* Practice Section.
*
* #package Lawyer_Landing_Page
*/
$section_title = get_theme_mod( 'pratice_section_page' );
$post_one = get_theme_mod( 'practice_post_one' );
$post_two = get_theme_mod( 'practice_post_two' );
$post_three = get_theme_mod( 'practice_post_three' );
$post_four = get_theme_mod( 'practice_post_four' );
$posts = array( $post_one, $post_two, $post_three, $post_four );
$posts = array_diff( array_unique( $posts ), array('') );
if( $section_title || $posts ){
?>
<section class="practice-area">
<div class="container">
<?php
lawyer_landing_page_get_section_header( $section_title );
$qry = new WP_Query( array(
'post_type' => array( 'post', 'page' ),
'posts_per_page' => -1,
'post__in' => $posts,
'orderby' => 'post__in',
'ignore_sticky_posts' => true
) );
if( $posts && $qry->have_posts() ){ ?>
<div class="row">
<?php
while( $qry->have_posts() ){
$qry->the_post(); ?>
<div class="col">
<div class="box">
<?php if( has_post_thumbnail() ){ ?>
<div class="icon-holder">
<?php the_post_thumbnail( 'lawyer-landing-page-practice' ); ?>
</div>
<?php } ?>
<div class="text-holder">
<h3 class="sub-title"> <?php the_title(); ?></h3>
<?php
the_excerpt();
?>
</div>
</div>
</div>
<?php
}
wp_reset_postdata(); ?>
</div>
<?php
}
?>
</div>
