Based in pride and sin, humanity believes that they can obey all that the law of God commands and obtain their own righteousness. But as Dr. Martyn Lloyd-Jones argues with Acts 7:37–38 in the sermon “The Law of God,” this is a complete misunderstanding of what the law is and why God gave it to His people. God never intended for His people to obtain righteousness by the works of the law and the blood of animals that could never atone for sin. But as the apostles taught, God gave the law in order to convict all of their need for salvation and redemption. The whole of the law points not to humanity and their ability to do what God commands, but it points to the need of a Savior. It points to one who can obey the law for those who cannot. This man is Jesus Christ. He came to fulfill all that the law required. The sacrificial system looked forward to His death on the cross as a sacrifice for all who would believe. This is the gospel: Jesus Christ saves those who cannot save themselves. He stands in their place before God so that they may have life and fellowship with Him. By believing in Jesus, the Christian has new life through His sacrifice.
