* If a person has a "clear conscience" it means that he is not hiding any sin.
* If someone ignores their conscience and no longer feels guilty when he sins, this means his conscience is no longer sensitive to what is wrong. The Bible calls this a "seared" conscience, one that is "branded" as if with a hot iron. Such a conscience is also called "insensitive" and "polluted."
* Possible ways to translate this term could include, "inner moral guide" or "moral thinking."
