There is therefore now no condemnation to those who are in Christ Jesus, who do not walk according to the flesh, but according to the Spirit.
Romans 8:1
There is no condemnation for those who do not walk after the flesh.
Those who practice the works of the flesh, will not inherit the kingdom of God.
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,
21 envy, 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
These are the same Galatians that Paul warned about falling from Grace.
Those that practice the works of the flesh, will not inherit the kingdom of God.
Those that inherit the Kingdom, will hear these words on the Day of Judgment;
Then the King will say to those on His right hand, 'Come, you blessed of My Father, inherit the kingdom prepared for you from the foundation of the world: Matthew 25:34
If you do not inherit the kingdom of God, then you will hear these words on the Day of Judgement;
Then He will also say to those on the left hand, 'Depart from Me, you cursed, into the everlasting fire prepared for the devil and his angels: Matthew 25:41
Paul warns these Galatians just a few verses earlier - You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace. Galatians 5:4
17 For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, so that you do not do the things that you wish. 18 But if you are led by the Spirit, you are not under the law. Galatians 5:17-18
... that those who practice such things will not inherit the kingdom of God.Galatians 5:21
Christians who do not inherit the kingdom, because they have practiced the works of the flesh, have fallen from Grace.
