being darkened in their understanding, alienated from the life of God because of the ignorance that is in them, because of the hardening of their hearts.
Context
17 This I say therefore, and testify in the Lord, that ye henceforth walk not as other Gentiles walk, in the vanity of their mind,
18 Having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart:
19 Who being past feeling have given themselves over unto lasciviousness, to work all uncleanness with greediness.
