It is for God to judge, not for us

11 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. 12 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?

James 4 (NASB)
