When I was in college, I attended a worship group meeting one day because one of my (at the time) favorite professors was giving a talk. He discussed the importance of making sure that the classes, and the subject matter you're studying for them, relate to your beliefs. That is, one should be constantly asking oneself, "How does what I'm studying in this class relate to my faith?" Even things like the formation of ionic bonds should be considered alongside a belief in God.
This idea struck me at the time as being really difficult. However, being a philosophy major, I felt like everything that I studied was mostly meaningful and significant...But, how was a biology major to relate their studies to God? Now, I see how important it is to make sure that what we are studying or working as (in my case, a waitress) is in line with my beliefs. That is, I should be a humble servant while I am waiting table (i.e. be nice and not complain about customers). Seems simple, but it has very good and very far-reaching branches. The way in which we work, the attitude towards even mundane tasks, can reflect our beliefs and a sense of integrity.
Today, I was awoken early by some inspectors. The building I rent is being resold so the potential new owners are making sure the building is sound, I guess. One of the inspectors was very friendly and made the intrusion less invasive seeming. On his way out, he dropped off a couple of packets of dip-mix that his wife makes and puts together. I'm sure they'll be very delicious. I thought to myself, this man is finding a way to connect with people in his job, he's finding a way to include Christ in his work--most of which involves inspecting crawl spaces and running tests, fairly mundane things. I hope to be able to do the same.
