James 4:13-17 - Arrogant Boasting About The Future
13 Come now, you who say, "Today or tomorrow we will travel to such and such a city and spend a year there, and carry on business and make a profit," 14 you who do not know {what will happen tomorrow}, {what your life will be like}. For you are a smoky vapor that appears for a short time and then disappears.
15 Instead you should say, "If the Lord wills, we will live and do this or that." 16 But now you boast in your arrogance. All such boasting is evil. 17 Therefore, to the one who knows to do good and does not do [it], to him it is sin.
