KJV Below (Link to NIV)
8 If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well:
9 But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors.
10 For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.
11 For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law.
James first clarifies, he’s not talking about reverse discrimination (i.e. we shouldn’t hate rich people just because they are rich), but that we should love everyone. It is called the “royal law” because it governs the kingdom of God. To drive home his point that failing to do so makes one a “sinner” he notes that failing to keep any one law is failure to the law as a whole. You have broken the covenant. This will lead him, in tomorrow’s reading, to a discussion of the different kind of life we live under the “royalty” who issued the royal law.
Do you like to think of yourself as a generally good person? Is there a danger in thinking highly of ourselves when, in reality, we have broken the covenant by any one error we make?
