James 4:13-17 NASB1995
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. 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.” But as it is, you boast in your arrogance; all such boasting is evil. Therefore, to one who knows the right thing to do and does not do it, to him it is sin.
