"Material World"

So today in school we had to write about 10-15 sentences and the title should be "Material World". Some of us didn't know how to start so teacher tried to explain. This was in religion class so teacher said that we should wrote about how some people cared about money and their appearance a little too much and on the other side how some people didn't care that much and cared about God more. She also said that the things material people did were usually sins.

I don't agree with her at all. I think that there are people who aren't material but that doesn't mean they have to believe in God. And material people can believe in God too,but also be obsessed about how they look, how much money do they have and what other people think of them. I didn't like how she put it that way that you can either be material or believe in God. What about people that are neither? Do they exist? I think so..what do you think?
