The Bloody Truth

Years ago when I was a worship leader, one of the pastors came to me and said, “You need to tone down the whole ‘blood’ thing.” We had sung Nothing But the Blood of Jesus and he told me it upset those who had come out of Satan worship. I had to disagree.

When you trace the theme of blood through Scripture, it becomes clear that God is teaching a single, consistent truth from Genesis to Revelation: sinners can only be reconciled to a holy God through a sacrificial death. The Bible does not present Christ’s blood as a theological afterthought that appears in the New Testament. Rather, from the earliest pages of Scripture, God is preparing His people to understand the necessity of substitution, sacrifice, and ultimately the shedding of blood for the forgiveness of sins.

The first hint appears immediately after the fall. Adam and Eve sinned, realized their nakedness, and attempted to cover themselves with fig leaves. Yet God replaced their inadequate covering with “garments of skin” (Gen 3:21). While the text does not explicitly mention blood, an animal had to die for that covering to be provided. Even here we find a picture that will echo throughout Scripture: human effort cannot adequately cover sin, but God provides a covering through the death of another.

The principle becomes clearer in the next generation. Abel offered to God “the firstborn of his flock and of their fat portions” (Gen 4:4), a sacrifice involving the death of an animal, and the Lord regarded Abel and his offering with favor. The writer of Hebrews later tells us that “by faith Abel offered to God a more acceptable sacrifice than Cain” (Heb 11:4). Already God is distinguishing between mere religious activity and an approach to Him that comes according to His appointed means.

The theme expands dramatically in the Passover. On the night God judged Egypt, Israel was commanded to kill an unblemished lamb and place its blood on the doorposts and lintel of the house. God’s promise was simple and profound: “When I see the blood, I will pass over you” (Exo 12:13). The Israelites were not spared because they were more righteous than the Egyptians. They were spared because they stood under the protection of the blood. Centuries later, Paul would identify Christ as the fulfillment of that picture, writing, “For Christ, our Passover lamb, has been sacrificed” (1 Cor 5:7).

Under the Mosaic Law, blood became the central element of Israel’s sacrificial system. Animals were offered daily, monthly, yearly, and on special occasions to make atonement for sin. The foundational explanation is found in Leviticus 17:11: “For the life of the flesh is in the blood, and I have given it for you on the altar to make atonement for your souls.” God explicitly states that He Himself appointed blood as the means by which atonement would be made. This was not man’s idea. It was God’s provision.

The Day of Atonement in Leviticus 16 further emphasized this truth. Once each year the high priest entered the Most Holy Place carrying sacrificial blood to make atonement for the sins of the nation. Yet these sacrifices had to be repeated year after year because they could never permanently remove sin. They pointed beyond themselves to a greater sacrifice yet to come.

The prophets continued to develop this expectation. Isaiah described a coming Servant who would bear the sins of His people. “He was pierced for our transgressions; he was crushed for our iniquities” (Isa 53:5). “The LORD has laid on him the iniquity of us all” (Isa 53:6). Isaiah presents a substitute who suffers in the place of sinners, foreshadowing the sacrifice of Christ.

When Jesus arrived, John the Baptist immediately identified Him with this long history of sacrificial imagery. Seeing Jesus, he declared, “Behold, the Lamb of God, who takes away the sin of the world!” (John 1:29). Every Passover lamb, every sacrifice on every altar, every ceremony performed by every priest was pointing forward to this One.

At the Last Supper, Jesus explicitly interpreted His approaching death in terms of sacrificial blood. Holding the cup, He said, “This is my blood of the covenant, which is poured out for many for the forgiveness of sins” (Mat 26:28). The forgiveness promised throughout Scripture would be accomplished through His blood.

After the cross, the apostles repeatedly explained salvation in those terms. Paul writes, “Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God” (Rom 5:9). He tells the Ephesians, “In him we have redemption through his blood, the forgiveness of our trespasses” (Eph 1:7). He tells the Colossians that God has reconciled sinners to Himself, “making peace by the blood of his cross” (Col 1:20). In each case, Christ’s blood is presented as the means by which God justly forgives sinners while remaining perfectly holy.

The book of Hebrews perhaps states the matter most directly. Looking back over the entire sacrificial system, the author concludes, “Without the shedding of blood there is no forgiveness of sins” (Heb 9:22). He explains that the blood of bulls and goats was never the ultimate solution. Rather, Christ entered the heavenly holy place “by means of his own blood, thus securing an eternal redemption” (Heb 9:12). Unlike the priests who offered sacrifices repeatedly, Christ “offered for all time a single sacrifice for sins” (Heb 10:12).

Peter echoes the same truth, reminding believers that they were not redeemed with silver or gold but “with the precious blood of Christ, like that of a lamb without blemish or spot” (1 Peter 1:18-19). John adds that “the blood of Jesus his Son cleanses us from all sin” (1 John 1:7).

The story culminates in Revelation, where heaven itself celebrates the saving power of Christ’s sacrifice. The redeemed sing to the Lamb, “for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation” (Rev 5:9). Later we are told that believers overcome Satan “by the blood of the Lamb” (Rev 12:11).

Taken together, these passages reveal a single scarlet thread running through the entire Bible. It’s not trivial. It’s not a matter of opinion. It’s not simply human tradition. From the garments of skin in Eden, to Abel’s sacrifice, to the Passover lamb, to the blood on Israel’s altars, to Isaiah’s suffering Servant, to the Lamb of God hanging on Calvary, Scripture consistently teaches that forgiveness and reconciliation come through a substitute who dies in the place of sinners. The Old Testament anticipated it. The New Testament announces its fulfillment. As Hebrews declares, “without the shedding of blood there is no forgiveness of sins” (Heb 9:22), and as John rejoices, “the blood of Jesus His Son cleanses us from all sin” (1 John 1:7). Jesus, at that last Passover, commanded we remember His shed blood forever (1 Cor 11:24-25). That is the Bible’s testimony from beginning to end.
