Hi,
You can use the below shortcode for accomplishing that.
[show_post_snippets post_type="post" number_of_columns=4 post_count=4 image_size='small' show_meta="false" layout_class="post-snippets full-width-snippets" excerpt_count=100 display_text="false" show_excerpt="true" hide_thumbnail="false"]
Here are more variations that are available.
