Keeping the law (chapter 2)

James said the royal law was to love your neighbor as yourself.  However, if you prefer the rich, you commit sins.  You are showing partiality.  You have to keep the whole law.  If you fail in one point, you are accountable for all it.  You are not supposed to kill or commit adultery.  If you do one or the other, you are still a transgressor of the law.  If you speak and act, you will be judged by the law of liberty.  If you have not shown mercy, there will be no mercy for you.  Mercy triumphs over judgment.  Do you keep the whole law?
