If you're going by the law, the basis of fruit is how you treat those who are least of all.
This is because you are acting benevolent for no selfish reason.
The Israelites however, are not a good comparison since they were not born again.
So are you now agreeing that God's law is His instructions for how to bear fruit for Him by teaching us how to treat those who are lest of all? How good or bad of a job that the Israelites followed God's law doesn't change that it is God's instructions for how to bear fruit for Him.
Paul said that if righteousness can come by the law, then Christ died in vain.
Perhaps this may hint at some absurdities in your theologies expressed.
I completely agree that we do not earn our righteousness as the result of obeying God's law and I have never suggested otherwise because that was never one of the reasons for why we should obey it, so that is not contrary to my position.
Where is it written exactly as you have said?
1 John 3:10 By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, nor is the one who does not love his brother.
God's law is His instructions for how to practice righteousness, such as by helping the poor and honoring our parents, and this is further supported by the fact that the context of 1 John 3:4-10 contrasts practicing sin in transgression of God's law with practicing righteousness in obedience to it.
I probably view your theology the same way. Not a problem.
You are free to think that, but if you are unable to explain how your position is not absurd, then the problem remains with your position. You are more that welcome to explain what it is that is innate to a command not to sin that magnifies sin instead of leading us away from sin or to explain why it is not absurd to think that Paul delighted in causing sin to increase.
The Spirit has the role of leading us to obey God.
Why do you say that the Spirit has the role of leading us to obey God, but stop short of saying that the Spirit has the role of leading us to obey what God has instructed?
Using Israelites as a comparison illustrates that the instructions expressed in your post are not for people born again by the Holy Spirit.
The Israelites are a light to the nations either by being an example of what we should do when they obeyed God's law or by being an example of what we should avoid doing when they disobeyed God's law, and we should learn from their example of disobedience what we should avoid doing (1 Corinthians 10:1-13). So regardless of the extent to which the Israelites did what is righteous or wicked, we should still have faith for God to correctly divide between the two through His law in accordance with the leading of the Spirit.
In Matthew 5:28, Jesus taught something that was more difficult than the law, it says that our intent to lust counts as the action of lust. This this not taught in the law, it is alluded to in Job.
What the law teaches on it is easier.
Jesus also taught, no divorce, and that the commandment to divorce was given because the hearts of the people were hardened.
Why then was he not stoned for blasphemy and for adding to God's teachings?
If what you said it correct, then you are arguing that Jesus sinned in violation of Deuteronomy 4:2 and is therefore not our Savior. However, if we correctly understand what is being commanded against by the 7th and 10th Commandments against adultery and coveting in our hearts, then we will not lust after a woman in our hearts, so Jesus was just teaching how to correctly obey those commands as it was originally intended, not adding to or subtracting from the law.
In Matthew 19:3, Jesus was asked whether a man was permitted to divorce a woman for any reason. For context, Gittin 90a-b interprets Deuteronomy 24:1-4 as saying that a man is permitted to divorce his wife if she ruins his meal or if he finds another woman who is prettier than her. It was this sort of divorce over frivolous reasons that was not the case from the beginning, so again Jesus was not making changes to what the Father taught in disagreement with Him.
Jesus was not stoned for blasphemy and for adding to God's teachings straightforwardly because he never did that.
