Romans 2:
[12] All who have sinned without the law will also perish without the law, and all who have sinned under the law will be judged by the law.
[13] For it is not the hearers of the law who are righteous before God, but the doers of the law who will be justified.
Scripture disagrees with you.
I think we are addressing two different topics in this part.
Soo… the topic of this thread has to do with “why?”, and I am saying that the question contains a false premise. When we use the word “justified” we are not talking about “why”, but “ought” and “what is our response/God’s response to sin”.
All men know the truth yet suppress it because they want to do evil.
If suppression of the truth is to be equated with knowingly and willingly rejecting God, then one could judge that someone else has K&WRG when they suppress the truth. However, if the person does not equate suppression of the truth with K&WRG, then in his own mind he is not K&WRG, even if I judge that he has. If he is unknowing, he is unknowing, and that is that. If he does not believe that God is equated with truth, even though we have told him a million times, then he is not K&WRG. Now, I may be compelled to blame him, and say “that is no excuse”, but that is beside the point, then we get into the territory of “ought”, when the topic of the thread falls under “is”.
I have daughters. They rage when they are not getting their way. That is not conscience, that is self-will. Conscience is the interior judge that tells them after they have raged that they ought not to have raged. They know that they ought not to rage, like when they’re told to clean their room or take the dogs out, but their anger comes from the belief that their time is their own, that they own every minute of a 24 hour day, and that when I ask them to take the 5 minutes to take out the dogs or the half hour to clean their room that their time for their own leisure is being “stolen” from them.

Yes, I agree. Lovely, aren’t they? Yes, they have their own rules, and we share many, like “my time is
mine”. Nobody wants to sacrifice their time, unless their rulebook (i.e. “I
should do my share” or Love compels them. Isn’t it nice when love, rather than guilt (from the conscience) compels them? “I am doing this because I like it when Mom and Dad have their need for order/cleanliness met.” Empathy plays a role in this ownership aspect.
Which has been my point, the conscience knows, but the will overrules. Why? Because the will is not dominated by the conscience or reason but by the passions, by base feelings and by sensual appetites.
I am in agreement with much of what you said there. The question is, what is the order of events? To me, we have the appetites, that is a given. The appetites do affect the mind; desire leads to blindness. Is this blindness
willed? In my own experience, the answer is “no”. It may
seem that I am purposefully rationalizing my own bad behavior, but it is desire itself that
compels me to do such rationalizing. And, unless I am experienced and aware of the compulsion, the rationalization seems like reality itself!
'Surely, I will not die"
Their apparent penchant for misbehavior is not due to uninformed conscience, but to self-will. They know that they ought not misbehave. And this is easily discovered when you ask the child, “don’t you know that you shouldn’t have taken that toy?” Their answer is never “no” but “yes”.
Yes, we must address the question, “why does the child misbehave even though she knows she ought not?”. Their mind is telling them “you want the toy”. Another voice says “if you do this, you will get in trouble - if you get caught.” Much comes into play concerning why the child follows the rules in the first place. When we say “follow the rules, otherwise you get punished”, then the child will take special care not to be discovered, the desire for stuff is constant. Eventually, though, the child learns that it is not so much that punishment is important, but that theft is a violation, the child who experiences something being stolen from her knows the grief, the hurt, the loss. The child who cares about his playmates will not want them to experience the loss. The child
takes ownership of the rule. This
ownership is the truly informed
conscience, in the way that I use the word. The child is connected to the law
intrinsic. Before then, it is not incorporated in the child’s conscience, it is “what the adults want me to do”.
1776 "Deep within his conscience man discovers a law which he has not laid upon himself but which he must obey. Its voice, ever calling him to love and to do what is good and to avoid evil, sounds in his heart at the right moment. . . . For man has in his heart a law inscribed by God. . . . His conscience is man’s most secret core and his sanctuary…
So, the conscience is formed through love, (empathy very important) and it is “deep within” and “discovered”. A child who obeys the law simply to avoid punishment has not reached the depths, has not discovered, and thus, is uninformed - in my reading. However, I am perfectly willing to accept a different read of the word “informed”.
