Jas 2:8  "If you really fulfill the royal law according to the Scripture, "You shall love your neighbor as yourself," you are doing well." 


You really know you are doing well, living and abiding in the love of God when it flows through you into love for others around you. You don't show them love in order to gain recognition. Your love flows naturally and all the glory received is given back to God. He is Absolute Love.
Sin raises its ugliness in doing supposedly "good" things in order to be recognized and have favor lauded upon us. You know what?; When we are not rewarded in the way we want by the ones we want the recognition from, we get angry we become guilty of murder. We may not have been sexually immoral, we feel like we are better than others in the morality department, but we are transgressors against the "royal law". Our love of others diminishes and dies. 



Mat 5:17-22  "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven. For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.  "You have heard that it was said to those of old, 'You shall not murder; and whoever murders will be liable to judgment.'  But I say to you that everyone who is angry with his brother will be liable to judgment; whoever insults his brother will be liable to the council; and whoever says, 'You fool!' will be liable to the hell of fire." 

I wouldn't want to face the justice of God if I was unmerciful to others here on earth. You see the prophets in the Old Testament say,  "woe, woe to you". Judgment is not only an Old Testament idea. Judgment is yet to come!

Heb 9:27, 28  "And just as it is appointed for man to die once, and after that comes judgment, so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him." 

To meet God without the presence and intercession of Jesus Christ, now that would be a big "WOE! Only the Mercy of God in Christ will triumph over our just judgment. 

Rom 3:19-25  "Now we know that whatever the law says it speaks to those who are under the law, so that every mouth may be stopped, and the whole world may be held accountable to God.  For by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin.  But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it-- the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction:  for all have sinned and fall short of the glory of God,  and are justified by his grace as a gift, through the redemption that is in Christ Jesus, whom God put forward as a propitiation by his blood, to be received by faith. This was to show God's righteousness, because in his divine forbearance he had passed over former sins." 

Jas 2:9-13  "But if you show partiality, you are committing sin and are convicted by the law as transgressors.  For whoever keeps the whole law but fails in one point has become accountable for all of it.  For he who said, "Do not commit adultery," also said, "Do not murder." If you do not commit adultery but do murder, you have become a transgressor of the law. So speak and so act as those who are to be judged under the law of liberty.  For judgment is without mercy to one who has shown no mercy. Mercy triumphs over judgment." 

Throw yourself on the mercy of God in Christ. He is Absolute Love. Then Abide in that Love!
