1 Thessalonians 4:9

7 For God has not called us to impurity, but to holiness.

8 Anyone, then, who rejects this command does not reject man but God, the very One who gives you His Holy Spirit.

Now about brotherly love, you do not need anyone to write to you, because you yourselves have been taught by God to love one another.

10 And you are indeed showing this love to all the brothers throughout Macedonia. But we urge you, brothers, to excel more and more

11 and to aspire to live quietly, to attend to your own matters, and to work with your own hands, as we instructed you.

Do read the surrounding verses too, because the context often says more than a single verse.
