18. Their moral understanding is darkened and their reasoning is beclouded. [They are] alienated (estranged, self-banished) from the life of God [with no share in it; this is] because of the ignorance (the want of knowledge and perception, the willful blindness) that is deep-seated in them, due to their hardness of heart [to the insensitiveness of their moral nature].
19. In their spiritual apathy they have become callous and past feeling and reckless and have abandoned themselves [a prey] to unbridled sensuality, eager and greedy to indulge in every form of impurity [that their depraved desires may suggest and demand].
20. But you did not so learn Christ!
