[11] Brothers and sisters, do not slander one another. Anyone who speaks against a brother or sister or judges them speaks against the law and judges it. When you judge the law, you are not keeping it, but sitting in judgment on it. [12] There is only one Lawgiver and Judge, the one who is able to save and destroy. But you—who are you to judge your neighbor? [13] Now listen, you who say, “Today or tomorrow we will go to this or that city, spend a year there, carry on business and make money.” [14] Why, you do not even know what will happen tomorrow. What is your life? You are a mist that appears for a little while and then vanishes. [15] Instead, you ought to say, “If it is the Lord’s will, we will live and do this or that.” [16] As it is, you boast in your arrogant schemes. All such boasting is evil. [17] If anyone, then, knows the good they ought to do and doesn’t do it, it is sin for them.
