I think the natural state of the Force means anyone can tap into it, but needs practice and training to use it effectively, and some are more naturally talented than others and use it instinctually.
But the Force has its own will, and can “raise up” someone (like Rey) in a crisis situation (“Darkness rises, and light to meet it”).
I’m with this except, maybe, that last part. I don’t like the idea that the Force can bend someone to do it’s will. Especially the Light side.
I also haven’t seen the movie, so that might not be what happens.
