is_home not functioning at all

I’m working on a new theme and the is_home statement is not working at all. It’s as if WP isn’t determining what the home page is. I’ve seen that this happens with static front pages, but this is a dynamic WP functioning page. I’ve included the sidebar code (where the conditional statement is) and a link to the compete page. Any suggestions would be great. Thanks.

<div id="sidebar">
	<ul id="events">
		<?php query_posts('cat=3'); ?>
		<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); $firstpost = $post->ID; ?>
		<li id="post-<?php the_ID(); ?>"><a href="<?php the_permalink() ?>" title="Read <?php the_title(); ?>"><?php the_title(); ?></a></li>
		<?php endwhile; else: endif; ?>
	</ul>
	<?php if (is_home()) {
	echo '<div id="about">';
	echo '<p>We are the youth ministry of <a href="https://www.fumc-orl.org/" target="_blank">First United Methodist Church of Downtown Orlando</a>. We seek to bring 6th through 12th grade students closer to God in a fun and relevant way. <a href="about/">Want to know more?</a></p>';
	echo '</div>';
	} ?>
	<p>test</p>
