James 4:11-17

11Speak not evil one of another, brethren. He that speaketh evil of his brother, and judgeth his brother, speaketh evil of the law, and judgeth the law: but if thou judgest the law, thou art not a doer of the law, but a judge. 12There is one lawgiver, who is able to save and to destroy: who art thou that judgest another? 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. 17Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
