No one is saying the law of sin, I am saying the law doesn't help you know how to live right.
Paul himself said the laws the ministration of condemnation: although Paul means nothing to me.
Let's stick to Jesus the author of our faith.
Moses did not fill up the cup, he left the cup half empty and really left it empty: because he never showed us how to do the things that were expected of us; he didn't show us that in order to live right before God you had to have a right heart and that in order to have a right heart you had to practice Mercy compassion forgiveness and Grace.
The don'ts of the Ten Commandments do absolutely nothing to help you know how to do what you need to: in order to be insulated and kept from violating the good. As has already been said Moses gave absolutely nothing to the Gentile Christian and truth be known he did absolutely no good to help the children of Israel be and maintain righteousness: all this is found in Christ and Christ alone and by this I mean in his teachings.
Really?
By faith Moses, when he was grown up,
srefused to be called the son of Pharaoh's daughter,25
tchoosing rather to be mistreated with the people of God than to enjoy
uthe fleeting pleasures of sin. 26
vHe considered the reproach of Christ greater wealth than the treasures of Egypt, for he was looking to
wthe reward. 27
xleft Egypt,
ynot being afraid of the anger of the king, for he endured
zas seeing him who is invisible. 28
ahe kept the Passover and sprinkled the blood, so that the Destroyer of the firstborn might not touch them.
29
bthe people crossed the Red Sea as on dry land, but the Egyptians, when they attempted to do the same, were drowned.
Hebrews 11 shows us otherwise.... By faith Moses considered the reproach of Christ greater wealth than the treasures of Egypt.... So what do you mean that Moses never showed us how to do the things that were expected of us? Moses was the instrument that God used to give His laws to Israel, right? I think also it was Moses that pleaded with God for the preservation of Israel. - remember His hot displeasure?
Mercy and compassion are both found in the law? the weightier matters... Do you not see this?
