Galatians 5:7, 15-17, 19-21

You were running [the race] well; who has interfered and prevented you from obeying the truth?

But if you bite and devour one another [in bickering and strife], watch out that you [along with your entire fellowship] are not consumed by one another. But I say, walk habitually in the [Holy] Spirit [seek Him and be responsive to His guidance], and then you will certainly not carry out the desire of the sinful nature [which responds impulsively without regard for God and His precepts]. For the sinful nature has its desire which is opposed to the Spirit, and the [desire of the] Spirit opposes the sinful nature; for these [two, the sinful nature and the Spirit] are in direct opposition to each other [continually in conflict], so that you [as believers] do not [always] do whatever [good things] you want to do.

Now the practices of the sinful nature are clearly evident: they are sexual immorality, impurity, sensuality (total irresponsibility, lack of self-control), idolatry, sorcery, hostility, strife, jealousy, fits of anger, disputes, dissensions, factions [that promote heresies], envy, drunkenness, riotous behavior, and other things like these. I warn you beforehand, just as I did previously, that those who practice such things will not inherit the kingdom of God.
