Give me a word, any word, and I show you that the root of that word is Greek.
For my pastoral colleagues who have given up and/or rusted up where their Greek is concerned, I recommend Keep Your Greek: Strategies for Busy People, by Constantine R. Campbell.
Here's a snippet for the utilitarian:
"Sometimes students ask me whether or not it is good to talk about Greek in their sermons. I usually caution against talking about it unnecessarily, though I think it is fine to do so if your hearers will really benefit. So then the inevitable question is: If Greek doesn't make it into my sermon, then what's the point? To which I will answer: If you think that way, you've missed the point. The usefulness of Greek is not so that you can tell people about what the Greek says in your sermon. The usefulness of Greek is that it will give you understanding of the text, which will shape what you do say in the sermon. It's for your preparation, and it usually remains behind the scenes. Sure, sometimes it might need to come out from behind the curtains, but generally speaking it will do its work unseen by everyone but you. But to you, the Bible teacher, Greek will make a huge difference."Preview Keep Your Greek here.
