James 4:13-17
13 Come now, you who say, “Today or tomorrow we will go into this or that city, spend a year there, do business, and make a profit.” 14 You do not know what tomorrow will bring. What is your life? Indeed, it is a mist that appears for a little while and then disappears. 15 Instead, it is better for you to say, “If it is the Lord’s will, we will live, and we will do this or that.” 16 But right now you are boasting in your arrogance. All such boasting is evil. 17 So, for the one who knows the right thing to do and doesn’t do it, this is a sin.
