In verse 13 James says, “Come now, you who say, ‘Today or tomorrow we will go to such and such a city, spend a year there, buy and sell, and make a profit . . .’” The words “Come now,” are intended to draw attention to what he is about to say. It’s like saying, “Come on now . . . do you really mean that?” In this verse James highlights the presumptuous claims that follow. His illustration of foolish boasting is framed by a series of positive confessions about what a person boasts will happen.
