Lacking awareness or purposely denying facts, assuming that there will be no repercussions, are pitfalls of shallow faith that the Gospels warn us about. If we want our final reward to be with God, we must become the loyal stewards that God desires us to be.
The conscience is like the captain of a ship who needs maps and reference points to navigate safely. The conscience cannot invent its own rules of morality. It needs a stable reference point independent of any individual’s whim or caprice. It needs to know what is truly good and what is truly evil so that it can judge correctly.
