The world has changed. Academic Courses can be obtained for free or a very very small fee. It is the diplomas and certificates and degrees that are the costly ones.
There is a true structure, which is God made, and a false structure, which is man made. The true structure comes from love, from the desire to learn the truth. The false structure comes from greed, ulterior motives and hypocrisy.
Q: Tim, I can find support for your seminary study...go go! Don't waste your time!
A: What makes you think I'm not studying now? Why don't you use that support for your own study?
Q: How are you studying?
A: This is a new kind of world now. Courses are offered free online, one can look up syllabus and follow the references, books are everywhere in library. Your notion of "Must have a teacher", "Must end up with a degree" is laughable.
Q: But going to seminary is still different...
A: I know what you're going to say...yes, having a teacher, even full time study, in class discussion, etc. there are differences. No doubt, one who does not go to an institute physically would miss out on this. But then again, tell me, which institute are diligently seeking such advancements on top of a Soli Deo Gloria focus? Or are you just jealous, because you went through all these and now the younger ones are getting if not more than what you've been through in a cheaper and less time consuming fashion? Don't worry, when the time and place is right, I shall enroll.
The principle of seek and ye shall find defeats those who make God's truth a mystery for others. In the end, it is those who fear God and diligently wish to grow in Him who gets the taste of His reward, while the others grind their teeth outside of the Kingdom of Heaven.
