'Ungodly' in the Bible

Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers,

but upholding and fully understanding the mystery [that is, the true doctrine] of the [Christian] faith with a clear conscience [resulting from behavior consistent with spiritual maturity].
