James 4:13-16
4:13 Come now, you who say, “Today or tomorrow we will go into this or that town and spend a year there and do business and make a profit.”
4:14 You do not know about tomorrow. What is your life like? For you are a puff of smoke that appears for a short time and then vanishes.
4:15 You ought to say instead, “If the Lord is willing, then we will live and do this or that.”
4:16 But as it is, you boast in your arrogance. All such boasting is evil.
