Ephesians 4:17–19
So I tell you this, and insist on it in the Lord, that you must no longer walk as the Gentiles do, in the futility of their thinking. / They are darkened in their understanding and alienated from the life of God because of the ignorance that is in them due to the hardness of their hearts. / Having lost all sense of shame, they have given themselves over to sensuality for the practice of every kind of impurity, with a craving for more.
1 Peter 4:3
For you have spent enough time in the past carrying out the same desires as the Gentiles: living in debauchery, lust, drunkenness, orgies, carousing, and detestable idolatry.
