How do we know that we are sinful according to Scripture?

The Apostle Paul in Romans makes it clear that we come to know sin through the law. The law provides a clear standard of what is good and right, and in doing so, it reveals our shortcomings and sinful desires. Paul emphasizes that, prior to understanding the law, he did not realize the true nature of his sin; it was the commandment that made sin come alive in him. In this way, the law acts not only as a guide but as a means of bringing awareness to our deep need for redemption from our sinful condition, highlighting our reliance on the mercy of Christ.
