That's how you're portraying people who don't appreciate KJ English as much as you. "Some who have less facility with the English language may struggle with the soaring, Shakespearean but somewhat archaic words and sentence structures."
They struggle because it's a different language, not because they have less facility with English.
That phrase also originates in the 17th century. Would you like to abandon it for a more modern usage, or do you find it a useful and compelling idiom despite not really knowing the etymology of it?
You'll find that you use idioms drawn from the KJV almost daily.
