How to make her like me more?

So far what she does is laugh at my jokes, goes along with what I say, always smiling at me, slight eyes dilation, flirts back when I flirt with her sometimes, and always look at me whether up close or across the room. What can I do to make her more into me? how to move up in our friendship? I think she is straight to by the way but idk an she is really religious sorta not preaching all the time but involved in things like youth group and does religion type things in school.
