Romanos 7:13

‘Did then that which is good become death to me? Certainly not! But sin, that it might be shown to be sin, by working death to me through what is good; that through the commandment sin might become exceeding sinful.'

Did this then mean that what was good had brought about death in him? By no means. It was not the Law which had done it, but sin. Sin, that it might be shown to be what it was, had worked death in him through what was good. What the commandment had done was to reveal the awful sinfulness of sin, and to make it even more sinful by arousing human passions so that they sinned even more. But the commandment itself was good, even though it was being misused by sin.
