'Guilty' in the Bible

let us continue to come near with sincere hearts in the full assurance that faith provides, because our hearts have been sprinkled clean from a guilty conscience, and our bodies have been washed with pure water.

and [see to it] that no one is immoral or godless like Esau, who sold his own birthright for a single meal.

Marriage is to be held in honor among all [that is, regarded as something of great value], and the marriage bed undefiled [by immorality or by any sexual sin]; for God will judge the sexually immoral and adulterous.
