Why is understanding the law's spiritual meaning important for Christians?

The spiritual meaning of the law is critical for Christians because it reveals our true condition before God. In the Sermon on the Mount, Jesus clarifies that righteousness is not merely about external compliance with the law but about the heart's intention—those who are angry without cause or lustful in heart are guilty of violating God's commandments. This understanding underscores the reality that no one can achieve righteousness on their own and emphasizes our need for a Savior. Christ's fulfillment of the law and His perfect obedience provide the righteousness we require to enter the kingdom of heaven. The law, when understood rightly, drives us to Christ for the grace and mercy we cannot earn on our own.
