Changing Excerpt to Full Post

Hello, take a look at the featured slider at youth-sermons.com. The problem is that it doesn’t show the full text of the post/page. How can I fix that? I have tried putting
<?php the_content(); >?
in place of
<?php echo($arr[$i]["excerpt"]); ?>
but still no luck. Any suggestions? The full code is below:

</div>
            <div class="banner">
            <h2><?php echo esc_html($arr[$i]["title"]); ?></h2>
            <?php echo($arr[$i]["excerpt"]); ?>
            <br class="clear" />
            <span><a href="<?php echo esc_url($arr[$i]["permalink"]); ?>"><?php esc_html_e('learn nore','SimplePress'); ?></a></span>
            </div>
