The concept cannot be understood without understanding the demand of the Law

Lutero says: 

Continuation:
(4) The concept cannot be understood without understanding the demand of the Law toward us. The Law is God’s expression of His righteousness and holiness such that “the Law is holy, righteous and good” (Rom 7:12; “The Law of the Lord is perfect” (Ps 19:7)). The promise of the Law is righteousness: “If we are careful to obey all this law before the LORD our God, as he has commanded us, that will be our righteousness.” (Deut 6:25). It is called the “Law of Righteousness” (Rom 9:31). The Scripture affirms that “those who obey the Law will be declared righteous” (Rom 2:13). Further, “The man who does these things will live by them” (Rom 10:5; Lev 18:5). The Law was “intended to bring life” (Rom 7:10) if obeyed in its entirety.

(5) The concept cannot be understood without understanding sin. If the Law is the reflection of God’s righteousness, sin or unrighteousness (wickedness) is the transgression of the Law. Thus, if the Law is broken the man will reap “unrighteousness” and that “Cursed is everyone who does not continue to do everything written in the Book of the Law.” (Gal 3:10; Deut 27:26). “Every mouth maybe silenced and the world held accountable to God” (Rom 3:20) under the Law. The conclusion therefore of Scripture is this, “Everyone who sins breaks the law; in fact sin is lawlessness” (John 3:4). The demand of the Law is perfect obedience because “whoever keeps the whole Law and yet stumbles at one point is guilty of breaking all of it” (Jam 2:8). Thus, Paul made it clear that “Jews and are Gentiles are all under sin” (Rom 3: 9). In other words, all human beings have been measured through the Law (Rom 3:20 i.e. “through the Law comes the knowledge of sin”) but all have transgressed the Law (Rom 3:19). Thus, “There is none righteous, not even one” (Rom 3:10).

  Hi Lutero, you said: 

  Continuation:

  Ok.
  

  The Law is God’s expression of His righteousness and holiness such that “the Law is holy, righteous and good” (Rom 7:12; “The Law of the Lord is perfect” (Ps 19:7)). The promise of the Law is righteousness: “If we are careful to obey all this law before the LORD our God, as he has commanded us, that will be our righteousness.” (Deut 6:25). It is called the “Law of Righteousness” (Rom 9:31). The Scripture affirms that “those who obey the Law will be declared righteous” (Rom 2:13). Further, “The man who does these things will live by them” (Rom 10:5; Lev 18:5). The Law was “intended to bring life” (Rom 7:10) 

  All that is true. And all that confirms what Nick said.
  

  if obeyed in its entirety. 

  It seems to me, that Protestants make a whole new gospel out of these 5 little words. Have you read in Scripture?
  

  1 John 1:9
  King James Version (KJV)
  9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. 

  Therefore, even if we do not obey the law in its entirety, but repent and confess our sins, we will be forgiven.
  
  Therefore also, if we do not obey the law in its entirety and obstinately continue in our disobedience, without repentance, we will be condemned.
  

  Revelation 22:12-15
  King James Version (KJV)
  12 And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be.
  13 I am Alpha and Omega, the beginning and the end, the first and the last.
  14 Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
  15 For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie. 

  (5) The concept cannot be understood without understanding sin. If the Law is the reflection of God’s righteousness, sin or unrighteousness (wickedness) is the transgression of the Law. 

  Absolutely!
  

  Thus, if the Law is broken the man will reap “unrighteousness” and that “Cursed is everyone who does not continue to do everything written in the Book of the Law.” (Gal 3:10; Deut 27:26). 

  Still true. Remember that the righteous man fall seven times AND GETS UP!

  Proverbs 24:16
  King James Version (KJV)
  16 For a just man falleth seven times, and riseth up again: but the wicked shall fall into mischief. 

  That means that the righteous man will repent and ask forgiveness for his sins and be forgiven. The wicked man will continue in his sins.

  
  

  “Every mouth maybe silenced and the world held accountable to God” (Rom 3:20) under the Law. The conclusion therefore of Scripture is this, “Everyone who sins breaks the law; in fact sin is lawlessness” (John 3:4). 

  True.
  

  The demand of the Law is perfect obedience because “whoever keeps the whole Law and yet stumbles at one point is guilty of breaking all of it” (Jam 2:8). 

  Wrong. The GOAL of the law is perfection of the man of God:
  

  Matt 5:
  48 Be ye therefore perfect, even as your Father which is in heaven is perfect. 

  But God knows that we are not perfect and has thus provided for us a way out:
  

  Ezekiel 18:21
  King James Version (KJV)
  21 But if the wicked will turn from all his sins that he hath committed, and keep all my statutes, and do that which is lawful and right, he shall surely live, he shall not die. 

  All we need do is repent of our sins and God will forgive us.

   
  

  Thus, Paul made it clear that “Jews and are Gentiles are all under sin” (Rom 3: 9). In other words, all human beings have been measured through the Law (Rom 3:20 i.e. “through the Law comes the knowledge of sin”) but all have transgressed the Law (Rom 3:19). Thus, “There is none righteous, not even one” (Rom 3:10). 

  That verse is taken out of context. Obviously, there are many who are righteous. St. Paul is referring to the unfaithful and unbelieving people. The are not righteous. But Scripture refers to many who are righteous. Just one example:
  

  Luke 1:6
  King James Version (KJV)
  6 And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless. 

  Therefore, unless you make Scripture contradict itself, St. Paul is speaking about the wicked people who do not believe in God and disobey His Commandments willfully.
