James 4:13-15

13Come 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”;

14whereas you do not know what will happen tomorrow. For what is your life? It is even a vapor that appears for a little time and then vanishes away.

15Instead you ought to say, “If the Lord wills, we shall live and do this or that.”
