I would like my writing to be sophisticated, but find it difficult. I think this is since I have trouble understanding sophisticated passages. So no matter how well I know grammar, I can never arrange words in ways clever enough to call them sophisticated. Since the problem is actually my reading comprehension -- and I find many passages of the King James Bible difficult to understand, though not because some words of its words are archaic -- I need to improve my reading comprehension skills.
Let me just clarify that I don't mean to write in convoluted ways, but simply in ways sophisticated enough to delight myself and the reader.
I do not know if this is possible, but since this corresponds to writing ability, and since the following is therefore an acceptable question, at least according to my hope, I ask you this: How can I measurably improve my ability to comprehend difficult passages, in order to improve my ability to write them as well? Thank you.
