'Those who are not secure in Christ cast about for spiritual life preservers with which to support their confidence, and in their frantic search they cling not only to the shreds of ability and righteousness they find in themselves, but they fix upon their race, their membership in a party, their familiar social and ecclesiastical patterns and their culture as means of self-recommendation. Their culture is put on as though it were armor against self-doubt, but it becomes a mental strait-jacket which cleaves to the flesh and can never be removed except through comprehensive faith in the saving work of Christ.'
Richard Lovelace in Timothy Keller, Counterfeit Gods, p.140.
