There are two basic approaches to Greek studies. One is practical, the other mystical. One is obligatory, the other voluntary. One is utilitarian, the other creative. One is work, the other play.
Interestingly, either approach can succeed. The first is successful because it is concerned with the outcome. The other is successful because it is concerned with the process. In the first, the goal is a grade. In the second, there is no purpose behind the language beyond the language itself. The first pursues an education. The second pursues a dream and sees the degree as a mere by-product.
This explains why Greek classes have two basic types of students. Some have to study Greek. Others love to study Greek. For some, Greek is an inconvenient and boring use of their time. For others, Greek is something that is creative and playful. Like Paul on the road to Damascus, the latter have been converted to a completely different way of life. We see this even in those who teach us. Some Greek profs teach Greek because they must. For others, Greek is the reason they were born, and joy cannot be attained without it. Students know the difference.
Apparently I was born with a built-in love of Greek. I cannot explain that. It's a pure absurdity. Yet no one can persuade me that it isn't true. "Retirement" can retard the gift but not eradicate it.
Whether your reason for taking Greek is practical and just a matter of "gettin' 'er done," or the focal center of your Christian walk, I wish you success. Remember: in life it's not how long you lived that matters, but the way you played the game. Each of us must answer this question for ourselves. I teach Greek because it's the right and true thing to do. My task is to be as faithful to that calling as long as I have breath.
