James 4:11-17  NAS

Do not speak against one another, brethren.  He who speaks against a brother or judges his brother, speaks against the law and judges the law; but if you judge the law, you are not a doer of the law but a judge of it.  There is only one Lawgiver and Judge, the One who is able to save and to destroy; but who are you who judge your neighbor?

Come now, you who say, "Today or tomorrow we will go to such and such a city, and spend a year there and engage in business and make a profit."  Yet you do not know what your life will be like tomorrow.  You are just a vapor that vanishes away.  Instead, you ought to say, "If the Lord wills, we will live and also do this or that."  But as it is, you boast in your arrogance; all such boasting is evil.  Therefore, to one who knows the right thing to do and does not do it, to him it is sin.
