Entries on Summary/Want to Show Full Post

I am designing a blog for a client. The theme that we used and modified is Orange Squash. It is located here: https://www.pineblossomswebsites.com/blog/

My client wants to have the full posts show on the front page, but presently only the teaser shows. The settings in the dashboard are set to Full Text. Can someone help me with the coding?

Here is the coding for the index.
