Thematic Bible: Why the law was given

As then through one trespass all men have come under condemnation, so through one act of righteousness all obtain the gift of righteousness unto life. For as through the disobedience of the one man the many were made sinners, so through the obedience of the one man will the many be made righteous. Moreover the law came in in addition, that the trespass might abound; but where sin abounded, grace abounded much more; read more.
that as sin reigned in death, so grace might reign through righteousness to everlasting life, through Jesus Christ our Lord.
