Obey God from heart

Romans 2:17-29
Before teaching, he who should obey what he is teaching.
A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical. No, a person is a Jew who is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code. Such a person’s praise is not from other people, but from God.
The Jews will be saved neither by the laws nor by circumcision.
They pride them selves in God and law.
They know what God wants them to do - but do they actually keep the law? If not ,they might as well not been circumcised'. The real Jew is one who obey God from heart.
Why?
We boast nothing except Jesus christ.
Obey God with actions to honor God's name.
Race,circucusion and law are not the idendity to Christians.
How?
Obey God from heart and really keep the law.
