Galatians 5:16 - 18

"So I say, live by the Spirit, and you will not gratify the desires of the sinful nature. For the sinful nature desires what is contrary to the Spirit, and the Spirit what is contrary to the sinful nature. They are in conflict with each other, so that you do not do what you want. But if you are led by the Spirit, you are not under law." NIV translation

If you are in Christ, then, "YOU ARE NOT UNDER LAW" but that is not the end of your freedom. You can make the choice to "live by" (walk in) the Spirit which means that you can truly turn your life over to Christ and win the battle against the sinful nature (flesh). 

The flesh and the Spirit are at war with each other so, if you will heed the prompting of the Spirit in your daily life, you will be given the power to overcome whatever has a hold on you.

Galatians 5:19 - 21

"The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God." NIV translation

We have a list of things here but, as Paul said, they "are obvious". It is interesting to note that he says those who "live like this" and not those who do this. This reminds us that God forgives sins and He will forgive these things and by the power of the Spirit these things can be overcome. Those who live in these things refers to the fact that they are doing these things regularly and are content with their life. If you are walking in the freedom of Christ, you will not be bound to these things and they are not the pattern of your life.
