James 4:13-15 KJV
Go to 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: whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away. For that ye ought to say, If the Lord will, we shall live, and do this, or that.
