Saint Paul's word's do not seem hard to understand, as long as you do not come to them with preconceived Protestant conclusions:
Now the works of the flesh are obvious: immorality, impurity, licentiousness, idolatry, sorcery, hatreds, rivalry, jealousy, outbursts of fury, acts of selfishness, dissensions, factions, occasions of envy, drinking bouts, orgies, and the like. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.These words were written to those who had faith, not to unbelievers. There is no exception: "unless you have faith." Our Lord himself declared: "Not everyone who says to me, Lord, Lord, will enter the kingdom of heaven, but only the one who does the will of my Father in heaven." If one were to really believe the Bible then he must take these words as they are. I will accept what is written in the Bible, and not the man-made traditions of the Protestant reformers.
You would do an amazing service to yourself, if you would take time to outline the entire 6 chapters of Galatians. It would give you a keen understanding of the whole message and how the sections contribute to that whole.
That said, here is a short answer.
Now the works of the flesh are obvious: immorality, impurity, licentiousness, idolatry, sorcery, hatreds, rivalry, jealousy, outbursts of fury, acts of selfishness, dissensions, factions, occasions of envy, drinking bouts, orgies, and the like. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.
People who practice these kinds of sins are not true believers.
Again, if you examined the whole book, you would benefit, instead of picking out things that seem to say what you were taught.

Yes, the unsaved person lives like that and the unsaved will not inherit the kingdom.
But those born again are not of the flesh but of the Spirit.
Romans 8:9 You, however, are not in the flesh but in the Spirit, if in fact the Spirit of God dwells in you. Anyone who does not have the Spirit of Christ does not belong to him.
And so alive in Christ.
