the law does not define morals
God's Law teaches what is sin. In this way it teaches what is moral & immoral by defining & explaining it.
What the law does is expose our sin
Practical knowledge of sin is through the law (Romans 3:20) & we would not know what is sinful if it was not specified in a commandment (Romans 7:7). The Law educates & lays a basis for judgment (Romans 3:19).
The moral constructs themselves predate the law
If moral constructs are based in the character & mind of God, & Law is based in the character & mind of God, then it seems imaginary that moral constructs are truly separate from Law, which is really instruction if we look at the root meaning of Torah. God is judging from the Garden onward & is still judging.
Romans 4:15 tells us there is no
violation if there is no law. Romans 5:14 tells us Adam committed
violation (same word) & sinned. There must have been law in Adam's time, even if it was simply the command God had issued to him & the marriage between 1 man & 1 woman, and????
So it is not law that defines what is right/wrong it is God
God defines what is right & wrong & makes it clear by some means (like verbally in the beginning) and in writing during Moses. Once again, before Moses Abraham was keeping Law & Adam violated Law.
goodness itself is a product of God which exists separate to law
But Law also exists in the mind of God & goodness is not a product of God it is a characteristic of God. He doesn't just produce goodness. He is goodness.
God predates the whole thing, before there was darkness and light there was God.
But now you're going to creation again when 1 John 1:5 tells us God is light. You seem to be mixing up what God produces and what God is. As Soyeong has said, the characteristics of God's Law are the same things said about God. I really don't think we can separate God's Law from God. God's Law simply instructs of His character, which He requires us to share.
I was recently researching the topic of sin again. It's interesting that at the root of the Hebrew word is the meaning, "deviation." Even the word I translated above as "violation" carries the basic meaning of deviation from an established boundary. Beyond this, as I recall from earlier personal studies, all the words we relate to this topic of sin, have to do with walking & tripping, stumbling, stumbling so as to fall, falling aside, etc. And then we have all the walking terminology & commands, and the straight or crooked paths, and the entrance through the narrow gate and walk along the narrow way/path.
I think one of our main problems with all this translating & interpreting is that we simply put our own thinking into it rather than just being as literal as we can and allowing God to say what He says. Then, we add a Greek concept of law into the mix, and we end up with more error.
God made man in His image and gave man instruction on how to willingly be conformed to His character. Man deviated. God gave more instruction & promises to bring man back onto the path. God's Law is a lamp for our feet instructing us how not to deviate, trip, stumble, fall... God is light and He's been giving man this light since the beginning.
You seem to be taking away the lamp.
Again, I don't think it is created. I see it as the eternal mind & character of God & when we have His character, we won't need written Law because His Law will also be our character. Until then, I'm happy to know God the Son came to give a living example of God's Law/character, explain it to the degree He did, and establish a system to conform us to it. I'm also happy I can still read it and know what He says is good & bad & look within and around me & judge according to righteousness to whatever degree He's illuminated me to be able to do.
Maybe we could break with the philosophy and have you state in very simple terms what you think the status of God's Law is today, post Crucifixion-Ascension & post destruction of the Temple.
