Well, I only have one traditional class (Psy), but I also have 2 online courses. I have brought up religion MANY times and at first I didn't know what my instructor or others would say, but there are a lot of us that share the same views and have the same beliefs. They're also not ashamed to talk openly about God and I LOVE that!
Now, bring religion into another group or class and just about everyone has different views/ beliefs.
I think that just openly talking about God is a great way to bring about faith.
