How do we know that redemption through blood is true?

The doctrine of redemption through blood finds its foundation in the consistent biblical narrative that underscores the importance of bloodshed for atonement. In Hebrews 9:22, it states, 'without the shedding of blood there is no forgiveness.' This principle is carried throughout scripture, beginning with the sacrificial system outlined in the Old Testament and culminating in Christ’s atoning sacrifice on the cross. The repeated mention of blood in both the Old and New Testaments serves to affirm that redemption can only be achieved through His sacrifice. The Passover in Exodus serves as an archetype for the sacrificial work of Christ, further affirming the truth that our redemption is solely through the blood of Christ.
