"For where envying and strife is, there is confusion and every evil work." (James 3:16) Also this: "For God is not the author of confusion..." (1 Corinthians 14:33a)
Confusion's interesting. I mean that literally. When you're within its swirling mass and unable to make heads or tails of anything, it's like a void that opens wider and goes down further even as you seek to make sense of where (you can't seem to) find yourself. But when you're outside its influence, looking dispassionately at a lump of pure confusion can surely teach you a lot about how the way you're called plays in to everything else going on in your area. That's one of the main reasons confusion happens, I should add. A perfectly good and rational desire we try and bring out in our own time and colored with motives that were stirred by those who didn't have our best interests at heart.
"For I fear, lest when I come, I shall not find you such as I would, and that I shall be found unto you such as ye would not: lest there be debates, envyings, wraths, strifes, backbitings, whisperings, swellings, tumults:" (2 Corinthians 12:20)
That word "tumults" is translated in the top verses as "confusion". Like a demonic party in your house and at your expense. "Cast out the scorner, and contention shall go out; yea, strife and reproach shall cease." (Proverbs 22:10) Sometimes one has to not only work at clearing up their thoughts according to God's word but also in rebuking anything left over that brought the confusing points of view in the first place. God's good for it. And it's usually, usually a very simple hinge that brings a branch or strain of thought that blossoms into full-blown confusion. Like a little lie or the like (that's what a taradiddle is, by the way). Look for it. As the Holy Spirit is the Spirit of truth, He'll clear the air.
That's pretty much all it is and it's what it becomes. And you don't really care about it after it's over. When seeking God's will for your life, I would say that confusion is like the inverse to where you want to be. What I mean is, if you sense confusion, you can be sure that there's something in the air that was either acted upon out of ignorance. Or else it's there meant to keep you ignorant. James cites "envy" and "strife" as the two things that are the catalysts to confusion. He says two verses prior that "if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth." The first course of action to clearing up the confusion in your mind and heart is to deal with these two things there, first. One little lie (and the belief therein) can conflagrate into a full-blown flumadiddle. God help you. Paul says "But if any man be ignorant, let him be ignorant." (1 Corinthians 14:38) No one else can clear it up for you but God.
"So it's my fault?"
It's my fault if I'm confused. That's a good place to start. When I seek to jump ahead and bend situations and circumstances to my favor and my will, effectively employing "envy" and "strife" (strife being the outworking of the desires borne out of envy), things around will cloud and occlude and become obtuse and abstruse. In other words, colored without by my wrong thinking within. And I don't mean to confuse. God may not be the author of confusion, but I sure have stirred up my fair share for my life.
If there's one word I have to describe God's voice, it would be clear. Lines and structure and rules. Time signatures (a paradiddle is a unique time signature in drumming). These things, while they don't keep out the spontaneity of the Holy Spirit, certainly need to be in place to clear up the confusion that would keep us from following God's will for our life.
