James 4:13-17 KJV

13 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 :
14 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 .
15 For that ye ought to say , If the Lord will , we shall live , and do this, or that.
16 But now ye rejoice in your boastings: all such rejoicing is evil.
17 Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
