I have an BA in theology, an MA in apologetics, and am about to have an MDiv. With that said . . .
BE VERY CAREFUL about getting a theology degree. Unless you are a part of a large denomination with a formal support structure (e.g., Southern Baptist, Presbyterian, Methodist), you will almost certainly not be able to get a job. I would strongly encourage you to get a degree that will get you a
job, and then go back and get an MDiv. Bible Baptist is a GREAT school, and an MDiv from there would do you a lot of good.
I say that because all of the jobs in theology will require an MDiv. Especially if you are very young. If you were in your thirties or forties and had kids, you could maybe get away with pastoring a small church with a BA. But as young as you are, it will be very difficult for you. Once you get the MDiv, doors start opening. You can easily get a pastorate (especially if you are willing to do bi-vocational work), you can teach at a local seminary, you can work as a Christian educator, you can become a chaplain, etc.
If you want to do some theological studies in your undergraduate program, find a good Christian university where you can take some courses on theology for your electives. Or, do dual enrollment. Take some classes from a local (ACCREDITED) Bible college that will transfer into your secular degree. That will help you immensely when you go on to do an MDiv.
Trust me - I understand the call to ministry and the desire to go to Bible college. Just think long and hard about it. If you go that route, make sure you have a strong mentor who is going to help you get into a paid position quickly. But all in all, remember that if God is calling you into ministry, it's a lifelong calling. Moses' training took forty years! It's good that you are ready to go--but be prudent. If you are interested in some secular career so that you can make a living
while you do ministry, then so much the better. And there's nothing unspiritual about that. Paul was a tent maker, after all . . .
I hope this has been helpful. Whatever you do, just do it for God's glory. Make a choice. Don't second guess things and play "what if." God's not in heaven worrying about whether or not you make the right or wrong choice. If He wants to you use you, He will. You just follow Him!
God bless
. Then there's my science guy in me...I really like astronomy. Just to watch the stars at night is just amazing. About every documentary I watch is about space. I'm just a big fan of space, stars, planets, etc... The science behind it, the complex chemicals that make stars, humans, etc... Just fascinates me.
