What role does lifestyle play in the ideology?  And, conversely, what role does ideology play in the lifestyle?  Another question: What eventually happens to a person who professes a certain ideology but whose lifestyle isn't consistent with what it teaches?  Bring this down to where we live: What do Christian standards have to do with being a Christian?  I believe the answer is "Everything."  Sooner or later, how we live indicates what we believe.  A tree is known by its fruit.  A person who models the lifestyle of the unsaved is identifying with the unsaved and is putting his salvation at risk.  Christian standards are the product of the Christian ideology.
