Displaying posts in a page

My website has a static frontpage (so as to make it look not like a blog), but I want to have a page titled “Blog” where all the posts will show up. In other words, I want to have a page that would serve the purpose of a regular front page in a blog.

I have a plugin that runs php code in a page, so I tried copying and pasting most of the code from the main index template.php file from my theme into the “Blog” page, but I couldn’t get it to work. It just shows up as a blank page.

What php code would I need to enter to say display posts like the front page does?

Thanks alot.
