Romans 5:20-21 — What is the purpose of the law and why did God give it to Moses? Listen to this sermon on Romans 5:20–21 titled “The Law Came In” as Dr. Martyn Lloyd-Jones uses Scripture to explain the main function of the law. He begins by explaining that the law was not made to justify or condemn, as some might believe. Before moving to the real purpose of the law, Dr. Lloyd-Jones points out three ways that the law impacts. First, it increases knowledge of sin by defining it. Second, it increases conviction of sin by opening eyes to it. And lastly, the law actually increases sin. The law shed light on sin and made it evident in the lives of people. Based on these three truths, Dr. Lloyd-Jones then reveals the purpose of the law: to bring people to Christ and help them see their utter need of Him and His salvation. The law is what opens eyes to who they are as sinners and shows the inability to save themselves from it. This is where one experiences the fullness of the grace Christ has to offer. Christians can find hope in knowing that where sin abounds, His grace abounds more.
