Having been to Bible School, thinking that I needed to set 2 years of my life aside to just study Bible related things, I would say, in retrospect that you don't need it.
You only need the School of the Spirit in real life everyday.
Bible School/Seminary is an unrealistic cocoon that does not have much to do with real life.
Most everything that I have learned that has any eternal value I learned in the School of the Spirit raising a family, going to work, interacting with the lost everyday.
Most of these institutions train you in such a way that you will be a supporter of Institutional Christianity.
If you want to find God's calling on your life, get with God. You don't need a Bible School/Seminary to know and understand and walk in God's ways. In many ways, they can be a detriment.
No matter what I or anyone else in this thread says to you, you have to hear God's voice. Can you hear His voice? You don't learn this in Bible Schools. You learn this on your own. You and the Lord, together.
The best way to learn is to start pressing into the Lord right where you are, spending a lot of time in prayer and His Word, being a Doer of the Word and walking as Jesus walked. Bible Schools, actually create a lot of textbook activity which results oftentimes in creating Hearers of the Word, Debaters, Theologians, Professional Clergy, etc. Is this what you want? Many people go to these schools for a career thinking that this is the way to be a minister.
In my opinion, based on experience and knowing many that have graduated from these schools, you would be better off, in spending your money on something that can help you earn a living and support your family if you have one or ever hope to have one. You are not suppose to earn a living off of the Gospel. Don't know if you have ever heard that or not, but you will certainly read about it in the NT.
Knowledge puffs up (grows our pride), but love edifies.
You don't need Bible School to learn to walk in love and walk as Jesus walked. However, you do need Seminary and a degree to have a religious career.
Bottom Line: Can you hear God's voice in your life?
