James 4:13-17

Come now, you who say, “Today or tomorrow we will go to such and such a town and spend a year there, doing business and making money.” Yet you do not even know what tomorrow will bring. What is your life? For you are a mist that appears for a little while and then vanishes. Instead you ought to say, “If the Lord wishes, we will live and do this or that.” As it is, you boast in your arrogance; all such boasting is evil. Anyone, then, who knows the right thing to do and fails to do it, commits sin.
