It's easy to want to find commandments in the New Covenant even when they don't exist. It's often said that we have to interpret the Bible through command, example, and necessary inference. The last one is dubious, because God doesn't play hide the commandment. In fact, what matters is very clear:

"Or 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 effeminate, nor homosexuals, nor thieves, nor the covetous, nor drunkards, nor revilers, nor swindlers, will inherit the kingdom of God. Such were some of you; but you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus Christ and in the Spirit of our God." (1 Cor 6:9-11).
