Hey trofimus! Been reading a lot of your posts lately.
Don't know that I have a real beef with the added word. NLT renders thought for thought in a lot of places, but they get it pretty accurate to my mind mostly. And God doesn't seem to pick over words with me but rather gives me...a broad conceptual understanding of things. Maybe just how my mind works and how He does it with me, don't know...
So, my current understanding of:
The useless conversation/way of doing things that we were taught by our parents and
We renounce the things hidden because of shame and
the useless spiritual principles of the world
I was taught to hide a lot. This is really just to be taught the "manners" of society, what is expected of you so relative peace can be kept. So I was taught to hide my anger, to not let others know they had angered me. Also was taught to...make myself look good at every possible time, which included sometimes exaggerating myself and my "good" qualities and also not showing emotions of anger, hurt, impatience, etc. Was even taught to deny ever having had these feelings to others. At the same time, I was taught the respectable and acceptable way to passively-aggressively "get even."
So...it was all just a big old can of nuts. Its a useless way of life to just cover up and hide everything and try to appear to be who I am not. It is also all hidden because of shame, hence: we renounce the things hidden because of shame. We learn by Him to not hide these things and play these games, these spiritual principles and useless ways we were taught. Instead, we begin to say: look, the emporer isn't wearing any clothes so why are we all pretending so hard?
When I began this openness and honesty with His help (this walking in the light of truth rather than useless deceits) I was prouder and more arrogant than I am now. So what happened was I saw the deceits (things hidden because of shame) in others but not in myself. So I went around very arrogantly calling out everyone in their "mannerful" deceits. Of course they just rolled their eyes at me because I was blind to my OWN fig leaves and they saw I was also deceitful in my own self, doing what I'd been taught just as they were.
Then came painful humbling and seeing that the words needed to be applied to open my eyes to myself. Then it became more about honesty in myself rather than trying to force anyone else into honesty rather than deceits, those deceits being things like: no, I wasn't mad, no you didn't hurt my feelings, no I didn't intend what I said meanly, no I wasn't gossiping I was just very concerned, no I wasn't impatient.
So renouncing the things hidden because of shame is just...refusing to any longer walk in the self-deceits and hidden revenges but instead to walk in honesty, renouncing that useless way, those elemental principles for how we should be, do and act and to just walk in the truth concerning when we see them in ourselves. That's where I currently am in my understanding of those verses though I'm not good at concisely explaining a darn thing.
