so do you have God's Law written on your heart? you know that the word Law is Torah right? so one more time, do you have God's Torah written on your heart? Have you studied God's Torah with all its commandments and teachings?
"part of our nature to know" I guess a convicted homosexual christian who in his heart does not believe he is doing anything wrong has nothing to worry about right?
Christians have God's word and are without excuse, that's why we must always test the spirits, test our thoughts against Gods word.
Am saying we all, even the atheist, have God's law written on our hearts because He made mankind exist to know. love and serve Good/Him. One cannot make something to do something and not give that thing the ability to do that. It would be cruel to do that and expect that thing to know what is they are expected to do. The idea of mankind not being given the ability to know right from wrong is incompatible with saying that is part of our purpose for existence.
The convicted homosexual christian, presuming no mental impairment, knew what they were doing was wrong. Just like Adam did before he made his first sin part of our reality. Knowing something is wrong does not prevent us from doing it.Criminals do not commit crimes because they did not know it was wrong, they do it because they convince themselves first that they will not get caught/held responsible and they justify by lying to themselves that it really isn't wrong for them to do it.
If knowledge that something is wrong did stop people from doing a thing because it is wrong, then having that knowledge would completely limit our freewill and no one would sin. Obviously that is not the case. Hardening our conscience is part of a process we can do when any particular sin becomes habitual - and in that case we could perhaps talk about some (not total) mitigation of subsequent acts.
And think about it. How could God Judge the native peoples perhaps still existing today who live and die without ever hearing about what He did for them?
The answer is covered by the purpose for our existence - which is the same for all of us - which includes those same people.
And think about the Torah. God did not and will never change. So whatever else we believe about the Law, it cannot be true that Love God with all your heart and mind, then love others as yourself represents a "new" Law. In fact God Himself told us those two commands were not a "new" law. The Hebrew nation did not get a Torah because they need to know what was write and wrong, they got a Torah because they were stubborn and insisted on having everything spelled out for them in minute detail. Jesus said all of that Torah is covered if we but do two things. And those two things directly reflect the purpose for our existence - love, know and serve Good/Him.
So no human living at anytime in history from Adam down can stand before God and claim ignorance of what is right and what is wrong. Which is why none of need the answer for the question posed in the OP written down for us, in Scripture or anywhere else, to know the correct answer to that question.
