What is the significance of the blood in the Bible?

In biblical theology, blood represents life and atonement. Hebrews 9:22 expounds that 'without the shedding of blood, there is no forgiveness of sins.' The turning of the Nile into blood in Exodus 7 illustrates judgment but also foreshadows the sacrifice of Christ, whose blood provides true cleansing for sin. When Christians partake in the Lord's Supper, they remember Christ's sacrifice, acknowledging that His shed blood provides the only way to reconciliation with God. This dual aspect of judgment and redemption highlights the significance of blood in God’s salvific plan for humanity.
