Two types of people are uncomfortable with Matthew 7:1-6, those who use it as a way to do wrong without guilt and those who want to point out the faults of everyone but themselves.
Do not speak against one another, brethren. He who speaks against a brother or judgs 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? (James 4:11, 12 NASB)
