1 Thessalonians 4:7

4:6 that no one should take advantage of and defraud his brother in this matter, because the Lord is the avenger of all such, as we also forewarned you and testified.

4:7 For God did not call us to uncleanness, but in holiness.

4:8 Therefore he who rejects this does not reject man, but God, who has also given us His Holy Spirit.
