Romans 5:13

13 sin was indeed in the world before the law, but sin is not reckoned when there is no law.

Romans 5:13 In-Context

11 But more than that, we even boast in God through our Lord Jesus Christ, through whom we have now received reconciliation.
12 Therefore, just as sin came into the world through one man, and death came through sin, and so death spread to all because all have sinned—
13 sin was indeed in the world before the law, but sin is not reckoned when there is no law.
14 Yet death exercised dominion from Adam to Moses, even over those whose sins were not like the transgression of Adam, who is a type of the one who was to come.
15 But the free gift is not like the trespass. For if the many died through the one man's trespass, much more surely have the grace of God and the free gift in the grace of the one man, Jesus Christ, abounded for the many.
