Romans 5:20

"The Law came in so that the transgression would increase; but where sin increased, grace abounded all the more".

"The Law not only increases our knowledge of sin and not only strengthens our conviction of sin but because of what sin has done to us, it actually makes us sin and incites us to sin.

Because of what sin has done to us, because it has perverted our very nature and because it has such a grip on our hearts, the very Law that tells us not to do things creates within us a desire to do them all the more".
