ThemeREX Blogger is a custom shortcode for Visual Composer, which can output a blog post section anywhere on your site.
It's available under the ThemeREX tab, when adding a new visual composer element.
The shortcode can pull data from regular blog posts, as well as custom post types and pages. You can also narrow down the selection by specifying a post category, tag, or post ID.
In order to find an ID of a specific post or page, open it up in the admin panel, and in the URL address locate the part where it says "post=xx". The "xx" would be the number of your post.
E.g., on the image above, the post ID is 3131.
