"If . . . you are fulfilling the royal law, according to the Scripture, 'You shall love your neighbor as yourself,' you are doing well" (James 2:8).
Love is the only antidote for partiality.
In Matthew 22:36 a lawyer asked Jesus which commandment was the greatest. Jesus answered, "'You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.' This is the greatest and foremost commandment. The second is like it, 'You shall love your neighbor as yourself.' On these two commandments depend the whole Law and the Prophets" (vv. 37-40). Love for God and one's fellow man summarizes the intent of God's law, and is the measure of true faith.
Jesus wasn't calling for the shallow, emotional, self-oriented love that is so prevalent in our society, but for a sacrificial quality of love that places the needs of others on par with your own. That kind of love is utterly incompatible with partiality, which seeks only to further its own selfish goals.
Showing partiality breaks God's law because it violates God's attributes, misrepresents the Christian faith, ignores God's choice of the poor, and condones the blasphemous behavior of the rich (James 2:1-7). But when you treat others impartially, you fulfill the royal law. "Royal" in James 2:8 translates a Greek word that speaks of sovereignty. The law was given by God, who is the supreme authority in the universe, so it is authoritative and binding. Love fulfills God's law because if you love someone, you won't sin against him.
Apparently not all of James's readers were showing partiality, so he commended them, saying they were "doing well." The Greek word translated "well" speaks of that which is excellent. They were doing an excellent thing because they were acting in a manner consistent with God's impartial, loving nature. That's God's call to every believer: for "the one who says he abides in [Christ] ought himself to walk in the same manner as He walked" (1 John 2:6). As you do, you fulfill God's law and thereby prove that your faith and love are genuine.
