Why Are We Spiritual?

A question came up in class yesterday about spirituality. The teacher asked us 'what made a person spiritual?' So now I'm asking you, as believers in Jesus Christ (or for those of you who aren't) what is it that you do, or don't do, believe, or seek that makes you a spiritual person? Does attending church three times a week do it? What about not drinking or attending movies? So for everyone reading...What is it that makes you a spiritual person and why?
