Consider your quote below where you describe what it is to be righteous.
Here we see that you are, by implication, saying that our faith is not counted for righteousness because works of the law are necessary to do righteousness.
However we see in scripture that in Christ, a Christian's faith is counted for righteousness (Rom 4:5), and that we're holy (Rom 11:16), perfected (Heb 10:14) and complete (Col 2:10). This contradicts your description of a Christian being crippled if they do not obey the law.
Clearly you see that nobody is righteous unless they obey the law of sin and death.
And as the law requires perfect obedience, then we see that without perfect obedience to the law you seem to be claiming we're unrighteous.
However, there seems to be variations offered by some legalists on what the law requires, in spite of the fact that there are no scriptures to back up such doctrines claiming that near enough is good enough under the law.
For example, Laodicea described how what level of obedience to the law is expected of us by God, is dependent on what "light" we are given. Do you agree with Laodicea on this?
So to help me understand your doctrine, are you suggesting that any SDA who obeys the law half the time is half righteous? Or is their righteousness dependent on what God expects as a minimum standard of obedience to the law given the amount of "light" they have received?
As to your question in the last paragraph.
First God's minimum standard is complete surrender and complete obedience. No sin is ok with God. Sin is to break the commandments of God, the word itself means "to miss the mark" what mark the commandments are the mark the standard. The law puts forth a standard and that standard puts all of us in sin and need of Jesus.
So If I know that and only obey God half the time then I am not surrendered to Christ and thus I will miss the mark and sin thus breaking the commandments.
There is no such thing as half righteous you are either righteous or not.
And there is only one way to be righteous and that is to receive by Faith the righteousness of Christ. Let me give an example:
If I steal and commit adultery and am convicted by the law that I have sinned and missed the mark. I have three options,
1. who cares Ill just keep going.
2. try real hard to stop stealing and committing adultery which will fail.
3. Accept Jesus as my substitute and in Faith claim his righteousness.
What are the results?
1. nothing changes still sins.
2. one becomes bitter, judgmental, disillusioned and fails still sins.
3. Freed in Jesus and no longer steals or commits adultery stops sin.
Jesus righteousness converts us by faith in Him. that is why John could say he who does righteousness is righteous. John understood that He who walks in Faith will be imputed with Jesus righteousness which converts the soul from sin to righteousness.
Its that simple,
He who stole and steals no more shows the work of God in Him.
She who committed adultery and does no more shows Faith in action.
It takes love to die for a friend, Jesus truly loved us. But it takes power to convert that friend, Jesus does that also by the same faith that we have in his death for our sins.
Jesus is the creator of the heavens and the earth, That sound like what we need Jesus to create in us a clean heart.
