Many students have at least a part-time job, but few are working in their field of choice. I've yet to meet an Outlet Mall employee who envisions keeping that job for the long-term. Instead, those jobs help cover rent and food and allow for some fun, but they are stepping-stones toward the ultimate prize of a career.
I've spent a lot of time thinking about careers lately, now that I'm privileged to teach the University Seminar course here at Texas State. A very helpful part of the Seminar is activities involving the PACE (Personalized Academic and Career Exploration) Center. Students are given resources with which to explore their interests and abilities and then develop a career plan based on the results. For some students, the experience has been an eye-opener. They came to college thinking they might try a career in business or in education, only to discover that they really should explore engineering or mass communication.
Obviously, a state university wouldn't use this language, but what students are discovering through the PACE process is what Christians call their vocation, a word derived from the Latin vocare. A job puts food on the table, but a vocation is the work to which God is calling you. It's not always obviously religious work; one's calling may be in business or in design, or even in cobblery. Luther is reported to have once said, "The Christian cobbler does his duty not by putting little crosses on the shoes, but by making the best shoes they can make and selling them at a fair price so their neighbors can have good shoes."
There is not a major in cobblery at Texas State, but every field of study can be a means by which God works in the world. For in whatever field in which you might major, there will be other people, the neighbors whom all of us are called to love. So study hard and know it will pay off; not always in a paycheck, but in a life well-lived, doing what you love and being a blessing to others. And in the meantime, enjoy your temporary vocation as a student at Texas State.
