Therefore, I tell you and insist on in the Lord not to live any longer like the gentiles live, thinking worthless thoughts.
They [gentiles that think worthless thoughts] are darkened in their understanding and separated from the life of God because of their ignorance and hardness of heart.
Since they have lost all sense of shame [desensitized], they have abandoned themselves to sensuality and practice every kind of sexual perversion without restraint.
However, that is not the way you came to know the Messiah.
Surely you have listened to him and have been taught by him, since truth is in Jesus. Regarding your former way of life, you were taught to strip off your old nature, which is being ruined by its deceptive desires, to be renewed in your mental attitude, and to clothe yourselves with the new nature, which was created according to God’s image in righteousness and true holiness.
Ephesians 4:17-24
