4:17 This I say therefore, and testify in the Lord, that ye henceforth walk not as other Gentiles walk, in the vanity of their mind, 4:18 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: 4:19 Who being past feeling have given themselves over unto lasciviousness, to work all uncleanness with greediness.
