Good reasoning about the bible. I think that we can educate ourselves, and the bible is one tool but I don't think it is necessary. There are many tools. Even the bible says that God's nature and law are visible in creation. I think in Romans.
I am confused about the language, though. Amharigna means Amharric, right? And Ge'ez is related or something like that?
Anyway, I was running over again Ark's question about believers doing wrong, and I think I have a much better explanation - more complete.
What I see is that it has to do with power and responsibility. We cannot be held accountable for what is not within our power, because that is not our responsibility. So sometimes when a believer slips up in his thinking and forgets to remember Jah then he can do wrong things, but he is not to blame.
Basically, to be blameworthy you have to be fully responsible for the wrongdoing. And what I am saying is that a believer is always focused on Jah, so everything within his focus he puts Jah in front. But for things that he can't really understand he might do the wrong thing because of ignorance but never out of any evil intention.
So as I said, Jesus taught that it is the intention that is important (the spirit) and not the letter of the law (right and wrong). When you turn to Jah you are identified with Jah and christ, so you are focusing on him. So there is no evil intention, and there can be no condemnation.
Same thing I said before, but better I think.
