Featured Grid on Posts Page?

Hello,

Does anyone know how to get the featured grid onto the posts page rather then the front/home page?

I have a site in which case the “blog posts page” is set on a “static page” but the grid only seems to work on the homepage regardless.
I’ve tried:

<?php
	if ( is_page ( 'blog' ) && twentyfourteen_has_featured_posts() ) {
		// Include the featured content template.
		get_template_part( 'featured-content' );
	}
?>

But that doesn’t work. Also tried with ID but no luck.
Any ideas would be appreciated.
