Show entire posts on homepage.

I purchased the “revolution music” theme from a wordpress theme website and basically the items on the homepage are not shown fully, instead its a little excerpt and a picture (https://www.strikemma.com)

Can someone tell me how I can modify this code so that on the homepage it shows the Entire Posts instead of a sample and a read more button. I also want to make sure its only showing posts in category “23”.

This is the current code to the homepage

<?php get_header(); ?>

<div id="content">

	<div id="homepage">

		<div id="homepagetop">

			<div class="hptabber">

				<h3>Mixed Martial Arts News</h3>

				<!--This is where the thumbnails are found for the homepage bottom section - note the custom field name for this image is "hpbottom". Recommended image size is 70x70, as the stylesheet is written for this size.-->

				<?php $recent = new WP_Query("cat=23&showposts=7"); while($recent->have_posts()) : $recent->the_post();?>
				<?php if( get_post_meta($post->ID, "hpbottom", true) ): ?>
				    <a href="<?php the_permalink() ?>" rel="bookmark"><img style="float:left;margin:0px 10px 0px 0px;" src="<?php echo get_post_meta($post->ID, "hpbottom", true); ?>" alt="<?php the_title(); ?>" /></a>
				<?php else: ?>
				   	<a href="<?php the_permalink() ?>" rel="bookmark"><img style="float:left;margin:0px 10px 0px 0px;"  src="<?php bloginfo('template_url'); ?>/images/thumbnail.png" alt="<?php the_title(); ?>" /></a>
				<?php endif; ?>
				<b><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></b>
				<?php the_content_limit(350, "[Read more]"); ?>

				<div style="border-bottom:1px dotted #2255AA; margin-bottom:10px; padding:0px 0px 10px 0px; clear:both;"></div>

				<?php endwhile; ?>

				<!--This is where you can specify the archive link for each section. Replace the # with the appropriate URL-->

				<b><a href="https://www.strikemma.com/category/mixed-martial-arts-news/" rel="bookmark">Read More Mixed Martal Arts News...</a></b>
