Very well. Please show me the passages that backup your claim. You can use English, been a while since I studied Greek. I will start

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, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. 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.

Is NKJV acceptable translation for you? I know the NIV is a bit more accurate so I understand if you want to use that instead.
