Christians dating Non Christians

We're going to be having a study regarding this topic at my youth and I would love to hear all of your opinions, comments, Bible verses, anything to help with the teaching. This is something that I've struggled with in my life, so I asked if I could help lead this study. It should be interesting, we're also going into the whole "flirt to convert" "praise and pick-up" all those sorts of things that we've all tried or heard about. We'll see what happens.
