Read the second part of Dr. Clark's response to the question 'who should go to seminary?'. May I suggest that you carefully pay attention to point two in his response - don't go if you're just doing it to jump through a hoop, get your ticket punched or if you're only interested in 'practical ministry' stuff. I completely echo Dr. Clarks comments about seminary being the beginning of the process of learning, not the terminus. I learned how to think biblically in seminary, not just what to think.
I think I'll post later this week on how to get the most out of your seminary experience. I think it will apply to your classes at IU as well.
