Show full posts on home page, not excerpts

I want my blog home to show full posts instead of just excerpts, but I’m not sure how to change it. Normally, the solution is to change the_excerpt to the_content in the loop, but the loop uses get_template_part instead, like this:

<?php while ( have_posts() ) : the_post(); ?>
                        <?php get_template_part( 'content', get_post_format() ); ?>
                    <?php endwhile; ?>

get_template_part seemed to be referring to a section in content.php that addresses excerpts:

<div class="loop-entry-excerpt">
            	<?php the_excerpt(); ?>
            </div><!-- .loop-entry-excerpt -->

        </div><!-- .loop-entry-details -->

    </article><!-- .loop-entry-entry -->

Except changing the_excerpt here to the_content doesn’t help. Any help would really be appreciated!
