How do we know we cannot fulfill the law?

The inability to fulfill the law is a fundamental truth highlighted in the Scriptures. Romans 3:10 makes it clear: 'there is none righteous, no, not one,' which means every human being falls short of God’s standards. The law reveals our sinfulness rather than providing a means for justification. As we strive to obey God's commandments, we quickly discover our shortcomings, underscoring our need for a Savior. The law leads us to Christ because it shows us that we cannot achieve righteousness through our efforts.
