Come now, you that say, Today or tomorrow we will go into such a city, and continue there a year, and buy and sell, and get gain: Whereas you know not what shall be tomorrow. For what is your life? It is even a vapor, that appears for a little time, and then vanishes away. For you ought to say, If the Lord wills, we shall live, and do this, or that. (James 4:13-15)
