Sorry Brother,
You clearly were mistaken about the "intellectual dishonesty" of the King James Version , with its clear reference to those who walk not in the flesh.
Those who walk in the flesh are clearly disobedient.
Those who live their lives gratifying the lustful desires of the flesh will not inherit the kingdom of God.
19 Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness, 20 idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies, 21envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that those who practice such things will not inherit the kingdom of God. Galatians 5:19-21
8 No, you yourselves do wrong and cheat, and you do these things to your brethren! 9 Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, 10 nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. 11 And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God. 1 Corinthians 6:8-11
This phrase in Romans 8, fits perfectly with the context of the rest of Romans 8 as well as the letters that Paul wrote to the Gentile Churches, who had to be warned about falling back to there former behavior.
