Featured image not showing on home.php

I cant work this one out for the life of me. The following code works great on my page.php, but cant get the same result on home.php

<!-- Main component for a primary marketing message or call to action -->
      <?php $feat_image = wp_get_attachment_url( get_post_thumbnail_id($post->ID) ); ?>
      <div class="jumbotron" style="background-image: url('<?php echo $feat_image; ?>');">
        <div class="banner-box"><h1><?php $meta_value = get_post_meta( get_the_ID(), 'meta-text', true ); echo $meta_value; ?></h1></div>
      </div>

Anyone?
