James 2:8 If you really fulfill
the royal law according to the Scripture, “You shall love your neighbor as yourself,” you do well; 9 but if you show partiality, you commit sin, and are convicted by the law as transgressors.
The royal law is the greatest commandments - love God, love neighbor and that is shown by
keeping the commandments of God. 1 John 5:2-3
The law of liberty is the Ten Commandments- James is only contrasting and quoting from the Ten, just like when God wrote and spoke the Ten Commandments- He added no more.... this is a direct reference to the
Ten Commandments
10 For whoever shall keep the whole law, and yet stumble in one
point, he is guilty of all. 11 For
He who said,
“Do not commit adultery,” also said, “
Do not murder.”
Now if you do not commit adultery, but you do murder, you have become a transgressor of the law. 12
So speak and so do as those who will be judged by the law of liberty
The Ten Commandments is what we will be judged by and the law that defines sin Romans 7:7. The same law that is in God's heavenly temple Rev 11:19 under the mercy seat of Jesus. James was teaching the principle of what Jesus taught....not to break the
least of the commandments. Jesus came to amplify the Ten Commandments, not destroy and the commandments that He personally wrote, personally spoke, kept as our example and condemned others for keeping their rules above these commandments Mat 15:3-9, defines sin and what we will be judged by are absolutely written in the heart of God's New Covenant believers- our salvation is from sin Mat 1:21, how can we overcome sin, if we do not have the law of God in our heart and mind, we can't and rebelling against God's holy commandments is not recommended. Rom 8:7-8
Mat 5:19
Whoever therefore breaks one of the least of these commandments, and teaches men so, shall be called least in the kingdom of heaven; but whoever does and teaches them, he shall be called great in the kingdom of heaven. 20 For I say to you, that unless your righteousness exceeds
the righteousness of the scribes and Pharisees, you will by no means enter the kingdom of heaven. 21 “
You have heard that it was said to those [d]of old, ‘You shall not murder, and whoever murders will be in danger of the judgment.’ 22
But I say to you that whoever is angry with his brother [
e]without a cause shall
be in danger of the judgment. And whoever says to his brother, ‘Raca!’[
f] shall be in danger of the council. But whoever says, [
g]‘You fool!’ shall be in danger of [
h]hell fire. 23 Therefore if you bring your gift to the altar, and there remember that your brother has something against you, 24 leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift. 25 Agree with your adversary quickly, while you are on the way with him, lest your adversary deliver you to the judge, the judge hand you over to the officer, and you be thrown into prison. 26 Assuredly, I say to you, you will by no means get out of there till you have paid the last penny. 27
“You have heard that it was said to those of old, ‘You shall not commit adultery.’ 28
But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart. 29 If your right eye causes you to
sin, pluck it out and cast
it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell. 30 And if your right hand causes you to
sin, cut it off and cast
it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.
Not sure Jesus can be any clearer. Jesus is establishing important principles right from the Ten, that He warns not only should we not break the least of these commandments, but we are responsible for our teachings of others to not break the least of these commandments.
You don't need to find the word "Ten" to know which law is being referred to. The Ten Commandments came in its own unit that God placed together that no man has authority to add to or subtract from because man is not above God and His divine works Exo 32:16 Exo 31:18 Deut 4:13, Deut 4:22, Exo 34:28. The mention of one commandment in the Ten means its referring to this unit- the same one where James said you break one only quoting and contrasting from this unit of Ten you break them all and where Jesus said not to break the least of these commandments. This really shouldn't be a hard concept unless one is intentionally trying to miss it.
Rev 22:14
Blessed are those who do His commandments, that they may have the right to the tree of life, and may enter through the gates into the city. 15 But
outside are dogs and sorcerers (Breaking commandment #1Exo 20:3) and sexually immoral (breaking commandment #7 Exo 20:14) and murderers (breaking commandment #6Exo 20:13) and idolaters (breaking commandment #2Exo 20:4-6), and whoever loves and practices a lie (breaking # 9 Exo 20:16 or any of the commandments 1 John 2:4)
