My friend over at Rotundus has been taking some courses over at Biblical Training.
The courses are taught by some of the big, and smaller, guns of Reformed and Conservative Evangelical Theology. One class called Practical Theology by John Piper looks well worth the effort (if I only had the time!)
Mr. Rotundus has wondered aloud what the value of a seminary (or unseminary) educated computer scientist would be. I think it would have the same value as the Puritans espoused: a man walking behind the plow knowing his Bible, knowing his God, and worshiping his king. It makes one a better worker (since you begin to see God as the only boss worth pleasing), more motivated (his glory is our object), and keeps our handle on the word fresh. All to say, don't go off to seminary, but get filled up with all the good things God has for you in Christ, through the word, through free tools!!
