Question 91: How did Jesus fulfill God’s Law?

Question 91: How did Jesus fulfill God’s Law?

Jesus fulfilled God’s Law by obeying it perfectly in thought, word, and deed, and by bearing its penalty on our behalf through His sacrificial death. As the sinless Son of God, He lived in perfect righteousness and offered Himself as the spotless Lamb, satisfying the demands of divine justice and securing redemption for all who believe. (Matthew 5:17, Galatians 4:4–5, Romans 5:19, 2 Corinthians 5:21, Hebrews 4:15)

Expanded Explanation of Catechism Question

Jesus Christ fulfilled God’s Law in two great ways: first, by living a life of perfect obedience, and second, by offering Himself as the atoning sacrifice for sinners who had broken the Law. He did not set the Law aside, but honored it fully, as the only man who ever kept it without sin.

In His life, Jesus loved the Lord His God with all His heart and loved His neighbor as Himself (Matthew 22:37–40). He never transgressed a single command. As the Second Adam, He succeeded where the first failed, fulfilling the covenant of obedience (Romans 5:19). This righteousness is imputed to believers by faith, as part of our justification.

In His death, Jesus fulfilled the Law’s penalty. The Law demands death for sin (Ezekiel 18:4), and Jesus, though sinless, bore our guilt as the Lamb of God. He satisfied the justice of God (Romans 3:26) and opened the way for mercy to flow freely.

Article XV of the Thirty-Nine Articles declares: “Christ in the truth of our nature was made like unto us in all things, sin only except… who fulfilled the Law for us.”

J.C. Ryle wrote: “The Lord Jesus has not only paid the Law’s penalty, but He has also obeyed its precepts. He is our Substitute not only in death, but in life.”

Dr. Michael Horton, a Reformed Anglican theologian, explains: “Jesus not only died for our sins; He lived for our righteousness. His active obedience—His sinless life—is as essential to our salvation as His death.”

This is why Christ is called our Righteousness (Jeremiah 23:6). In Him, the demands of the Law are not relaxed, but fulfilled—in both justice and mercy. As a result, believers are no longer under condemnation, for the Law’s requirements have been met in Christ (Romans 8:3–4).

This fulfillment also gives new meaning to the moral Law. No longer a means of condemnation, the Law becomes for us a guide in Christ, teaching us how to live in gratitude and holiness. Through Christ’s obedience, the Law is not abolished—it is glorified.
