Why is Christ considered our Sabbath?

Under the New Covenant, Christ is presented as our Sabbath rest. Hebrews 4 describes how we enter His rest when we cease from our works, just as God ceased from His on the seventh day (Hebrews 4:9-10). This rest points to a deep spiritual reality; Jesus stated, 'Come unto me, all ye that labour and are heavy laden, and I will give you rest' (Matthew 11:28). Our ultimate rest is found not in following rituals or a day but in a personal relationship with Christ, who has completed the work of salvation on our behalf, allowing us to rest in His grace and righteousness.
