How do we know that the law is not to blame for sin?

In Romans 7:12-13, Paul emphatically states, 'Wherefore the law is holy, and the commandment holy, and just, and good.' The law itself is not sinful; it is a reflection of God's holy character. Instead, the issue lies within us—our sinful nature. When sin encounters the law, it becomes evident that we are transgressors and guilty. Paul illustrates that the law's role is to expose our sinfulness, leading us ultimately to see our need for Christ, who fulfills the law. Therefore, the blame for sin rests solely with human transgressors and not with the law itself.
