“‘What are your multiple sacrifices to Me?’ says the Lord. ‘I have had enough of burnt offerings of rams and the fat of fed cattle; and I take no pleasure in the blood of bulls, lambs, or goats’” (Isaiah 1:11).
Sacrifice is a significant theme through the entirety of scripture. While the Old Testament outlined an elaborate and detailed sacrificial system, the advent of Christ, and his atoning death as the Lamb of God who came to take away the sins of the world, rendered the old order unnecessary. Even so, the principle remains. No longer does God require the blood of dead animals but, rather, that we might present ourselves to him as living sacrifices (Romans 12:1). It is a one-to-one relationship — He died for us; we live for him.
