The term "Jesus' blood" in the Bible holds profound theological significance, primarily symbolizing redemption, atonement, and the establishment of the New Covenant. In Christian theology, Jesus' blood is seen as the sacrificial offering that cleanses believers from sin. This concept is rooted in the Old Testament sacrificial system, where blood was used to signify the life of the animal being offered to God (Leviticus 17:11). The New Testament emphasizes this connection, particularly in Hebrews 9:22, which states, "without the shedding of blood there is no forgiveness." Jesus' death on the cross is viewed as the ultimate sacrifice for humanity's sins, fulfilling the requirements of the Law and paving the way for salvation.Moreover, the blood of Jesus is closely associated with the institution of the Lord's Supper, where Jesus declares, "This is my blood of the covenant, which is poured out for many for the forgiveness of sins" (Matthew 26:28). This declaration highlights the establishment of a new covenant between God and humanity, signifying a shift from the old covenant based on the law to one founded on grace and faith through Christ. The blood of Jesus serves as a powerful reminder of God's love, the cost of redemption, and the hope of eternal life for believers, encapsulated in verses such as Romans 5:9, which asserts that "we have been justified by his blood."
