Come now you who say, “today or tomorrow we will go to such and such a city, and spend a year there and engage in business and make a profit.” Yet you do not know what your life will be like tomorrow. For you are just a vapor that appears for a little while, and then vanishes away. Instead, you ought to say, “If the Lord wills, we will live and also do this or that.” James 4:13-15 NASB
