let's see....if you break the law in any way, even in your thoughts according to Jesus, then you have sinned
so without the law, as scripture states, we could excuse our sin...so, your premise is wrong
Why then was the law given? It was added because of transgressions, until the arrival of the seed to whom the promise referred. It was administered through angels by a mediator. Galatians 3:19
Therefore no one will be justified in His sight by works of the law. For the law merely brings awareness of sin. Romans 3:20
the law makes you aware of sin...the opposite of what you say
If dealing with multiple chapters I would prefer to address one verse at a time. But I appreciate the fact that you did leave some scriptures this time to represent your point of view....
Galatians 3:19 - Context is very important... You can see from verses 16 and 18 that Paul is referring to law POST Abraham. When we see the word "law" in scripture it could be referring to man created law, god's law, laws given to specific people, etc. I don't remember if it was my initial post or one of my early responses, but I clarified that when I was speaking about law I was speaking of all instructions from the Father... From "be fruitful and multiply" to the holy days, the sabbath, commandments, etc. Yes, sin existed in the world before the laws that Paul was referring to here, but not before the very first laws. Adam had to be given the law not to eat of the tree, before sin could enter into the world.
Romans 3:20 - I believe the phrase "works of the law" would be better understood if it just read "what the law entails"... Some translations write "deeds of the law" here. The point is that just the knowing of the law shows us how much we are falling short... but this is not saying that doing the law does not effect our future blessings or curses.
Lets look at a verse from Paul in the previous chapter...
Romans 2:13 - For it is not merely those who hear the Law who are righteous in God’s sight. No, it is those who follow the Law, who will be justified.
How Romans 3:20 is commonly interpreted, it would appear to be in direct contradiction with Romans 2:13.... But Romans 3:20 is just pointing out the first half of Romans 2:13... how merely KNOWING the law only shows how much we sin. The last half of Romans 2:13 points out that we are justified by actually DOING the law.
