Romans 5:15-20

Romans 5:15-20. But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many. And not as it was by one that sinned, so is the gift: for the judgment was by one to condemnation, but the free gift is of many offences unto justification. For if by one man’s offence death reigned by one: much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ.) Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon, all men, unto Justification of life. For as by one man’s disobedience many were made sinners, so by the obedience of one shall many be made righteous. Moreover the law entered, that the offence might abound.

Just as, sometimes, a physician may give a medicine which causes the disease to be more fully developed in order to its ultimate cure, so does the law make a discovery of our sin to us, and it also excites us to greater sin, by reason of the enmity of our nature, which is opposed to the law of God, and becomes the more active the more clearly the law is known, even as Paul says, further on in this Epistle, "I had not known lust, except the law had said, Thou shalt not covet."
