"Subjective" means it depends on the individual person, and so is different for different people. In contrast, "Objective" means independent of the individual person, and so it's the same for all people.
Since you've also redefined objective and subjective, all your arguments about it were even more subjective and meaningless than they appeared to be? Wow.
When a person comes up with opinions of how things "should be" there is no reason for it to be morally binding on others. After all, other people can come up with different systems. It's subjective.
And that's still the case for your opinions or what ancient people wrote. But some laws may be binding if you get caught. Societies can still change their laws, yes.
If God were merely a very powerful individual as you've suggested, the situation wouldn't change much.
Especially when its power is the attribute of a mythological being. He's been generally rather powerless, he was not able to improve your wisdom or to convince or to find convincing evidence to witness about... He was powerless when people called for help and protection but were still hurt or murdered. He was powerless when people begged for protection against disease for them and their loved ones. Because of this, there are justifications, like only praying for what he already decided he would provide, only hope, nothing.
But God is actually the Creator of all that is.
In your particular theology it's a particular deity, yes.
He is sovereign. And He is the Judge.
Therefore you will not judge in his place?
All people will answer ultimately to God, and hence His rules are necessarily objective. They are the same for everyone, and binding on everyone because we all owe our existence to God and will answer to Him. Clear?
It's clear enough in words but not in practice. It's not even clear in words in the scriptures that you claim to be his word. That's also why you have all those Christian and Abrahamic schisms. Your deity is just not here to direct humans, so instead it's stupid mortal humans who always keep speaking and dictating what he allegedly would want, if he existed, in his name.
Then I agree with Swede. If you want to show that you're a good Christian, better get to work with the charity. You will be known by your fruits and so far your fruit is insanity and the worship of Mammon, so that may make some Christians fall...
