Ephesians 4:17-19

So I tell you this, and insist on it in the Lord, that you must no longer live as the Gentiles do, in the futility of their thinking. They are darkened in their understanding and separated from the life of God because of the ignorance that is in them due to the hardening of their hearts. Having lost all sensitivity, they have given themselves over to sensuality so as to indulge in every kind of impurity, and they are full of greed. 

you must no longer live as the Gentiles do 
Ephesians 2:1-2  As for you, you were dead in your transgressions and sins, in which you used to live when you followed the ways of this world and of the ruler of the kingdom of the air, the spirit who is now at work in those who are disobedient.

in the futility of their thinking 
Romans 1:21  For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened.

They are darkened in their understanding 
Deuteronomy 29:3-4  With your own eyes you saw those great trials, those signs and great wonders. But to this day the LORD has not given you a mind that understands or eyes that see or ears that hear.

and separated from the life of God 
Ephesians 2:12  ... remember that at that time you were separate from Christ, excluded from citizenship in Israel and foreigners to the covenants of the promise, without hope and without God in the world.

because of the ignorance that is in them due to the hardening of their hearts 
2 Corinthians 3:14  But their minds were made dull, for to this day the same veil remains when the old covenant is read. It has not been removed, because only in Christ is it taken away.

Having lost all sensitivity 
1 Timothy 4:1-2  The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons. Such teachings come through hypocritical liars, whose consciences have been seared as with a hot iron.

they have given themselves over 
Romans 1:24  Therefore God gave them over in the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another.

to sensuality so as to indulge in every kind of impurity, and they are full of greed 
Colossians 3:5  Put to death, therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires and greed, which is idolatry.
1 Peter 4:3  For you have spent enough time in the past doing what pagans choose to do--living in debauchery, lust, drunkenness, orgies, carousing and detestable idolatry.
