If you judge someone else, you have no excuse for it. When you judge another person, you are judging yourself. You do the same things you blame others for doing.
Do you make fun of God's great kindness and favor? Do you make fun of God when he is patient with you? Don't you realize that God's kindness is meant to turn you away from your sins?
But you are stubborn. In your heart you are not sorry for your sins. You are storing up anger against yourself. The day of God's anger is coming. Then his way of judging fairly will be shown.
But there are others who only look out for themselves. They don't accept the truth. They go down an evil path. God will pour out his burning anger on them.
Some people do not know God's law when they sin. They will not be judged by the law when they die. Others do know God's law when they sin. They will be judged by the law.
Those who aren't Jews do not have the law. Sometimes they just naturally do what the law requires. They are a law for themselves. This is true even though they don't have the law.
They show that what the law requires is written on their hearts. The way their minds judge them gives witness to that fact. Sometimes their thoughts find them guilty. At other times their thoughts find them not guilty.
Many are not circumcised physically, but they obey the law. They will prove that you are guilty. You are breaking the law, even though you have the written law and are circumcised.
No, a man is a Jew only if he is a Jew on the inside. And true circumcision means that the heart has been circumcised. It is done by the Holy Spirit. It is more than just obeying the written Law. Then a man's praise will not come from others. It will come from God.
