"But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath, tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;" (Romans 2:8-9)
The verb for doeth means to work out or produce. A man is known by his fruit. The unbeliever is characterized by continuously producing that which is against God's interest.
"But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile: For there is no respect of persons with God." (Romans 2:10-11)
In similar fashion, the one who is in Christ is characterized by working that which is good. This text is not claiming good works as a means of salvation but as a fruit of salvation. God's righteous judgment will ensure that all unbelief is punished and that all belief is rewarded. He is does not respect the faces of people. Respect of persons consists of two words. One means face, and the other means receiving or credit. God gives credit to no man's face. He is not impressed with the self-righteous countenance; He is only impressed by the broken countenance, for thus saith the LORD, "...but to this man will I look, even to him that is poor and of a contrite spirit, and trembleth at my word (Isaiah 66:2)."
