Romans 5:20 in the King James Version
Moreover the law entered, that the offence might abound. But where sin abounded, grace did much more abound:
Context
19 For as through the one man’s disobedience many were made sinners, even so through the obedience of the one, many will be made righteous.
20 The law came in that the trespass might abound; but where sin abounded, grace abounded more exceedingly,
21 that as sin reigned in death, even so grace might reign through righteousness to eternal life through Jesus Christ our Lord.
