WordPress security issue to output data from user input from theme option form

I have the following code (below) in my theme. I am using redux framework for my theme options. My codes in a part looking like this. And I am really not sure about the security issue of this chunk of codes. Please any expert help me indicating any security problem in here. Your few minutes from your life would be really appreciated and helpful.

<?php if (isset($cosomic_options['blog_tag']) && $cosomic_options['blog_tag'] ) { ?>
 <div class="entry-meta-tag">
    <?php the_tags('', ' ', '<br />'); ?>
 <?php } ?>

<div class="entry-content">
     <?php $content = get_the_content();
        echo wp_trim_words( $content , '35' ); 

<?php $continue_reading = ''; ?>
<?php if (isset($cosomic_options['blog_continue_en']) && $cosomic_options['blog_continue_en'] ) { ?>
                        <?php if (isset($cosomic_options['blog_continue_en']) && $cosomic_options['blog_continue_en'] ) {

                        if ( isset($cosomic_options['blog_continue']) && $cosomic_options['blog_continue'] ) {
                            $continue_reading = $cosomic_options['blog_continue'];
                         }else {
                            $continue_reading = 'Continue Reading';
                         } ?>

                        <div class="a-btn">
                            <a href="<?php the_permalink(); ?>"><?php echo $continue_reading; ?> <i class="fa fa-hand-o-right"></i></a>
                        <?php } ?>
    <?php } ?>

Security issues arise when you write code that open up possibilities for outsiders to access your database or otherwise compromise your installation.

The above code just reads options and content from the database and translates this into static html that will be send to the browser of the page’s visitor. There’s no code (like a form) that will allow the visitor to send information back to your server. So there are no security concerns.

(Of course there still could be vulnerabilities in other parts of your code.)

Redux framework has some issues but you can overcome it.
