I agree that the Bible is the Word of God, and that it's not a confusing book, but that the things therein signified are to the unspiritual impossible to be understood, because the Spirit of God is not in them. I also think that in my case, God has only revealed to me what He wants me to know, requiring me to study the things that already I am able to understand, or that in my case, I cannot understand structures syntactically complex, in which many Biblical passages are written, knowing that -- not to boast of my own ability, which is less than that of many -- although I'm able to write long sentence with clarity, yet I'm unable to write sophisticated ones, due to my lack of a sophisticated mind, my own mind even unable to concentrate on the things people say when conversing with me, although they are speaking with simplicity and plainness.
I obtained the ability to write this way through study of grammar and practice, and through recent practice in writing with utmost clarity and brevity, which was not concerned with rhythm at all, although I believe that God has enabled me to write as well as I'm able to, because, of any ability of mine, I ought never to boast, even as the Bible says, although it seems that through overmuch speech of it, I gloat. Forgive me. And, if I boast of a false gift now, forgive me also for this.
It is also possible that my medication, finally effective, has given me clarity of mind whereby I am able to do this better.
Also, I've been doing a little exercise almost every day.
I also read in the past some style guides, from which I obtained the knowledge of clarity and brevity, the rules of which I violate when necessary.
