Sight WPShower WordPress Theme Question

I am using the Sight WordPress Theme on my site, and I want to make it so that the home page blogroll displays full posts – right now it is displaying only a small piece of text and I would rather each post in full. The link is https://www.morganvicki.com

If anyone can help me with this or if anyone is having the same problem and could let me know that would be great.

Thanks!
