At the gym, one often sees "ego lifting." That's when you lift more weight than you should because you want to impress others. Sometimes I see "ego Greek." You don't need to mention the Greek word or tense from the pulpit, but you do it anyway. Frankly, most people aren't even faintly interested in technical language. They could care less about "the present passive imperative" in Eph. 5:18. It's not that the tense, voice, and mood of the verb "be filled" aren't important. They are! But you trying to bring up scholarly language may be counterproductive. Try to find simpler ways to say what you think is important.
Ego lifting may seem like a good way to impress others, but it's ultimately a self-defeating habit.
Likewise, don't NEVER use Greek from the pulpit. But when you do, make sure it's for a very sound reason.
