James 4:13-16

13Come now, ye that say, To day or to morrow we will go into such a city, and continue there a year, and buy and sell, and get gain: 14Though ye know not what shall be to morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away.1 15Instead of that ye ought to say, If the Lord will, we shall live, and do this, or that. 16But now ye rejoice in your boastings: all such rejoicing is evil.
