Pull your old shirt out over the jeans.
I haven't heard any sermons during my lifetime that were given in King James English. That does not mean the KJV should go away. It only means it should be well taught and explained. There is the KJ21 version that could work. Its format is bookish and its highlighting can be difficult to get used to, but it is still the King James. Look what has happened when misguided men offer 'modern' translations. There is no Word left in sermons. Many are not even given in Good American English. As far as I am concerned, all that new stuff is the true adiaphora. I think Luther said if someone calls the good old stuff adiaphora he should have a fight on his hands.
Don't dream it, be it.
