Notme,
Well, perhaps you might consider changing majors, depending on what you want to do for a living one day, or, simply finding something that interest you more. Generally speaking, a B.A. in English won't help you out too much career-wise unless you plan on being a reporter or going on to further graduate level studies.
However, being a recent college graduate, having studied both in secular and private colleges I'll say a couple benefits of education, no matter where you get one at.
1) You'll become more disciplined - Unless you are simply trying to just pass with a C average, the world of academia will force you to become intellectually disciplined. You'll learn to manage your time, become more goal-oriented, and the like.
2) You'll increase your ability to find the truth and facts - Having to read through book after book, and write paper after paper, will teach you how to dig through information, and find out things for yourself, instead of just believing everything anybody says.
3) It'll also give you critical thinking skills. - Having to constantly compare opinion against opinion will make you think.
4) Make you less timid when it comes to learning difficult things, and gives you confidence- Frankly, after having been through 5 years of undergraduate studies, and 1 1/2 years of graduate studies, I feel like I could learn just about anything I wanted to.
5) It'll make you a life-long learner - Well... hopefully so at least. If you carry the good things you learned in college through the rest of your life, you'll hopefully keep learning, which will make you adaptable. So that if 20 years from now your job should pack up and go overseas, you wont' fulfill the maxim: "an old dog cannot learn new tricks," and thus find yourself with the ability to get a new job.
6) It'll give you something interesting to say every now and then - Socially speaking, this can go a long way.
And I'm sure many other things could be added. But these are just some benefits I've personally found when reflecting upon my education. As far as what benefit it has for the kingdom? That'll depend on what you do with it. Education can open doors closed to many others, and thus allow you the chance to perhaps reach people who would otherwise remain unreached. Perhaps with your education you can land a better job, provide for your family, and help support a missionary or somebody else in need (I know many homeless people who need some help!), and thus, through finances influence the kingdom.
Just be sure to keep the faith. For 2 years I earned an Associates in Liberal Arts, and took classes steeped in secular thought, and sometimes, some of the things we learned were just ouright attacks on the faith. I took biology, geology, history, philosophy, mythology(!), and a number of English classes (where the Puritains are treated like the scum of the earth!). Many of the things I learned were difficult to learn, but I perservered in the faith just the same. That's not to say that sometimes I didn't go through some series crisis like testing of my faith.
It's difficult to hear about evolution and get to learn first hand some of the mechanics of that theory. It's difficult to hear about the skepticism philosophy casts on everything. It's difficult to hear about how Noah's flood was nothing more than a rehash of the Gilgamesh epic. Some of these things can shake one to the foundations. But, now that I've wrestled with those things, and consequently, with God, and come through those things, I am quite thankful to have received the liberal arts education that I have.
Now when some "intellectual" is ready to drop a bomb on me and my faith, they are quite shocked that I'm not really moved by these things anymore, and pretty much just give a "so what?" attitude to a lot of the arguments they might put forth. Frankly, this has been very important when I have gone to UNC Charlotte and the like to do some evangelism.
I see that you are from Greensboro. The Lord recently has called me to become a missionary to Greensboro. Starting in the Spring I plan on coming up there, and probably starting at UNC Greensboro, to do some evangelism. Perhaps we could meet sometime for some coffee.
God bless.
