What does it mean that Christ is our Sabbath rest?

The idea that Christ is our Sabbath rest means that He completed the work of redemption, granting believers peace and rest from striving for salvation through works. Hebrews 4:9-10 notes that there remains a rest for the people of God, which is realized in Christ. By trusting in His finished work, believers experience true spiritual rest as they are freed from guilt and the burden of the law. Just as the Sabbath pointed to a cessation of labor, Christ's sacrifice fulfills the requirements of the law, allowing us to rest in Him for our salvation.
