James 4:13-16

13Come now [and pay attention to this], you who say, “Today or tomorrow we will go to such and such a city, and spend a year there and carry on our business and make a profit.”

14Yet you do not know [the least thing] about what may happen in your life tomorrow. [What is secure in your life?] You are merely a vapor [like a puff of smoke or a wisp of steam from a cooking pot] that is visible for a little while and then vanishes [into thin air].

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

16But as it is, you boast [vainly] in your pretension and arrogance. All such boasting is evil.
