James 5:13-15
Look here, you who say, "Today or tomorrow we are going to a certain town and we'll stay there a year. We will do business there and make a profit." How do you know what your life will be like tomorrow? Your life is like the morning fog, it's here a little while, then it's gone. What you ought to say is, "If the Lord wants us to, we will live and do this or that."
