James 4:13-16 (NIV):
[13] Now listen, you who say, “Today or tomorrow we will go to this or that city, spend a year there, carry on business and make money.” [14] Why, you do not even know what will happen tomorrow. What is your life? You are a mist that appears for a little while and then vanishes. [15] Instead, you ought to say, “If it is the Lord’s will, we will live and do this or that.” [16] As it is, you boast in your arrogant schemes. All such boasting is evil.
