$Wp-customize Default content showing up in Customize menu not in Normal View

Question

I am developing a wordpress theme and i've created a couple of blocks with Echo and dynamic content that I can see in my Customize menu in Wordpress but in normal view I cannot.

<body>
        <div class="container">
            <div class="block1">
            <div class = "text">
            <h2><?php echo get_theme_mod('ViorelStanciu-text-headline')  ?></h2>
            <?php echo wpautop(get_theme_mod('ViorelStanciu-text-paragraph'))  ?>
              
    </div>
</div>
    <div class="block2">
    <div class="image">
    <img src="screenshot.png" alt="">
    </div>
    </div>
    <div class="block3">
        <div class = "text2">
        <h2><?php echo get_theme_mod('ViorelStanciu-text2-headline')  ?></h2>
        <?php echo wpautop(get_theme_mod('ViorelStanciu-text2-paragraph'))  ?>
    </div>
    </div>

Functions.php:

    $wp_customize->add_section('ViorelStanciu-grid', array('title' => '2x2 Grid'));
    $wp_customize->add_setting('ViorelStanciu-text-headline', array('default' => 'Where does it come from?'));
    $wp_customize->add_control( new WP_Customize_Control($wp_customize, 'ViorelStanciu-text-headline-control', array(
        'label' => 'Headline Top',
        'section' => 'ViorelStanciu-grid',
        'settings' => 'ViorelStanciu-text-headline'
    )));

    $wp_customize->add_setting('ViorelStanciu-text-paragraph', array('default' => 'Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.?'));
    $wp_customize->add_control( new WP_Customize_Control($wp_customize, 'ViorelStanciu-text-paragraph-control', array(
        'label' => 'Paragraph Top',
        'section' => 'ViorelStanciu-grid',
        'settings' => 'ViorelStanciu-text-paragraph',
        'type' => 'textarea'
    )));

    $wp_customize->add_setting('ViorelStanciu-grid-image', array('default' => 'screenshot.png'));
    $wp_customize->add_control( new WP_Customize_Cropped_Image_Control($wp_customize, 'ViorelStanciu-grid-image-control', array(
        'label' => 'Image',
        'section' => 'ViorelStanciu-grid',
        'settings' => 'ViorelStanciu-grid-image',
        'width' => 750,
        'height' => 500
    )));
    $wp_customize->add_setting('ViorelStanciu-text2-headline', array('default' => 'Why do we use it?'));
    $wp_customize->add_control( new WP_Customize_Control($wp_customize, 'ViorelStanciu-text2-headline-control', array(
        'label' => 'Headline Bottom',
        'section' => 'ViorelStanciu-grid',
        'settings' => 'ViorelStanciu-text2-headline'
    )));

The idea is that my Default content is not showing up when I open the website.
