Here is an illustration for you of something that I need help with.....
I am currently preaching a series through Philippians and I came across the Greek word "πείθω", so I was interested in how this word, as the root, was used in all of Paul's letters. So, I created a search parameter that just includes Pauls letter. And I received 46 results. But one of the things that I noticed was that the root "πείθω" is also where the word "ἀπειθής" comes in Romans 1:30 that is translated "disobedient".
In fact, about 11 times of the 46 times that "πείθω" is the root in Paul's letters, the translation is "disobedient", "disobey", etc.
Can someone explain to me this significance? And any suggesstion on how you might use this in your preaching? I am trying to figure out the root of words in L5.
