James 4:13-17

But who are you to judge your neighbor? Consider this, you who say, "Today or tomorrow we will go into that city, and certainly we will spend a year there, and we will do business, and we will make our profit," consider that you do not know what will be tomorrow. For what is your life? It is a mist that appears for a brief time, and afterwards will vanish away. So what you ought to say is: "If the Lord wills," or, "If we live," we will do this or that. But now you exult in your arrogance. All such exultation is wicked. Therefore, he who knows that he ought to do a good thing, and does not do it, for him it is a sin.
