James 4:13-16

Thomson(i) 13 Come, now, ye who say, Today or tomorrow we will go to this or that city, and spend a year there, and traffic, and get gain, 14 when you do not know what will be the result of tomorrow. For what is your life? For it is a vapour which appeareth for a little while and then vanisheth. 15 Instead of your saying, If it be the Lord's will, and we shall live, we will do this or that, 16 you now boast of your arrogant projects. All such boasting is evil. Therefore to know what is good and not do it, is a sin.
