Featured Image as Clickable Link

Hello –

I thought this would be simple but I’m struggling to accomplish this. I would like to link to the page/post with the Featured Images on my front page. I’m also unsure of which content.php I need to editing if I so – there’s 4 or so with calls to the post_featured_image and $featured and I’m unsure of which is applicable for the front page. I would greatly appreciate any input. – https://loveblossomsweddingflowers.com
