The Sacrificial Christ's Work is Complete (Bible Study)

 The Complete Work of Christ: Four Proofs of His Accomplishment

The complete work of our Lord and Savior, Jesus Christ. His mission on Earth was not left unfinished, but rather, He accomplished everything He set out to do. Today, we will explore four undeniable proofs that demonstrate the completeness of Christ's work. Let us delve into the Scriptures and discover the profound significance of each proof.

The sacrificial work of Jesus Christ stands at the absolute center of biblical revelation. His culminating mission on Earth was to offer an all-sufficient sacrifice for the sins of the world. In the biblical tradition, the priestly office always included two primary functions:

    1. Presenting offerings of worship and gratitude.

    2. Offering sacrifices for sin to bridge the gap between a Holy God and fallen humanity.

Jesus Christ is the perfect fulfillment of this office, acting as both the High Priest and the Lamb of God.

1. The Sacrificial Idea in Scripture

The concept of sacrifice permeates the entire Bible, from the coats of skin in Genesis to the "Lamb slain before the foundation of the world" in Revelation. Various theories have attempted to explain the origin and meaning of sacrifice.

1.1 Theories on the Origin of Sacrifice

    • The Gift Theory: Sacrifice is viewed as a bribe to win divine favor.

        ◦ Refutation: This contradicts the holy character of God. God cannot be bought. Furthermore, it fails to explain why the gift required the death of a living being.

    • The Sacramental Communion (Totemic) Theory: The idea of eating an animal to "assimilate" the divinity.

        ◦ Refutation: This is a pagan, materialistic concept with no basis in Genesis. Biblical revelation is spiritual, not magical or pantheistic.

    • The Homage Theory: Sacrifice is an expression of dependence and honor, not motivated by guilt.

        ◦ Refutation: This fails to explain the sacrifices of Noah (Genesis 8:20-21) or Job (Job 1:5), where the death of the victim was central to the ritual's acceptance.

    • The Symbol Theory: The death of the animal was merely a means to obtain blood, which symbolized communion.

        ◦ Refutation: It ignores the substitutionary nature and the visible suffering of the victim, which pointed to the gravity of sin.

    • The Piacular (Expiatory) Theory — The Biblical View: "Piacular" means expiatory. This theory holds that sacrifice involves vicarious substitution—the animal dies in the place of the sinner.

        ◦ Biblical Basis: The Mosaic system emphasizes atonement through blood: "For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar" (Leviticus 17:11).

2. The Divine Origin of Sacrifice

While the Bible does not explicitly record the very first command to sacrifice, several theological arguments suggest that expiatory sacrifice was a divine institution following the Fall.

    1. Human Invention: The human mind is unlikely to spontaneously invent the idea that shedding the blood of an innocent animal would appease a Holy Creator.

    2. Divine Revelation: If God intended to save, He had to reveal the means of salvation.

    3. Approved Worship: God always determines how He is to be worshipped. In Genesis 4:3-4, Abel’s sacrifice of the firstborn of his flock was accepted, while Cain's bloodless offering was not, implying a revealed standard.

    4. The Mosaic Institution: The complex sacrificial system given to Moses was clearly dictated by God, not evolved from human culture.

3. The Sacrificial Work of Christ

The entire Old Testament sacrificial structure was a "shadow of the things to come" (Hebrews 10:1). Jesus Christ fulfilled the reality of these shadows by occupying three roles simultaneously:

3.1 Christ as Priest

The Book of Hebrews explains that Christ is our Great High Priest. Unlike human priests who had to offer sacrifices daily for their own sins, Christ:

    • Is holy, blameless, and pure (Hebrews 7:26).

    • Does not offer repeated sacrifices but offered one sacrifice for all time.

    • Entered the heavenly Most Holy Place with His own blood.

3.2 Christ as the Expiatory Sacrifice

Unlike the blood of bulls and goats, which could only "cover" sin temporarily, Christ’s sacrifice was:

    • Unique: Never to be repeated.

    • Sufficient: Infinite in value because of His divine nature.

    • Definitive: It actually removes sin rather than just masking it.

4. Characteristics of Christ's Sacrifice

Theologians identify four essential pillars of Christ's work on the cross:

    1. Substitutionary: He died in our place. "For Christ also suffered once for sins, the righteous for the unrighteous, to bring you to God" (1 Peter 3:18).

    2. Expiatory: He removed our guilt. To expiate is to "cleanse" or "wipe away" the legal stain of sin.

    3. Propitiatory: He satisfied divine justice. Propitiation refers to the averting of God's righteous wrath by a fitting sacrifice (Romans 3:25).

    4. Definitive: It is finished. "But when this priest had offered for all time one sacrifice for sins, he sat down at the right hand of God" (Hebrews 10:12).

5. The Dual Dimension of Christ's Work

Christ’s work is characterized by a "dual action" in the heavenly court:

    • The Offering: He presented Himself as the spotless Lamb to die for sin.

    • The Presentation: As Priest, He presents the merit of His sacrifice before the Father as our Mediator.

In Christ, the Offerer and the Offering are one. He is the Mediator who stands between God and man, ensuring that the sacrifice He made on the cross is eternally effective for all who believe.

"He entered once for all into the holy places, not by means of the blood of goats and calves but by means of his own blood, thus securing an eternal redemption." — Hebrews 9:12

This in-depth Bible study explores how the sacrificial system of the Old Testament served as a divine "blueprint" or "shadow," designed to be fulfilled by the person and work of Jesus Christ.

The Sacrificial Work of Christ: Symbolized and Typified

The sacrificial work of Jesus Christ did not emerge as an isolated event in the New Testament. It was carefully symbolized, announced, and typified by the sacrificial rituals of the Old Testament. The Mosaic system was never intended to be the final destination; it was a "shadow" of things to come. Christ is the "substance" or reality that the shadow pointed toward.

1. The Expiatory and Vicarious Nature of Sacrifices

To understand the Cross, we must first understand the altar. Various academic interpretations attempt to explain Old Testament sacrifices, but many fall short of the biblical text.

1.1 Insufficient Interpretations

    • Gifts to appease God: Viewing sacrifice as a "bribe" to win divine favor.

    • Communion Meals: Seeing the ritual merely as a social meal between the deity and the worshiper.

    • Symbolic Confession: Viewing the death of the animal only as a visual aid to show that sin is "bad."

    • Refutation: These views fail to explain the necessity of blood, the strict requirements for a spotless victim, and the explicit biblical language of substitution.

1.2 The Piacular (Expiatory) Character

Scripture demonstrates that sacrifices were piacular—meaning they were designed to make atonement for sin. This is most evident in the "Sin Offerings," but it is present throughout the system.

Biblical Evidence:

    • Explicit Statements: Leviticus 17:11 declares, "For the life of a creature is in the blood... it is the blood that makes atonement for one’s life."

    • Laying on of Hands: In Leviticus 16:21-22, the priest laid hands on the victim, symbolizing the transfer of guilt from the sinner to the substitute.

    • Sprinkling of Blood: This represented the "covering" (kippur) of sin before the eyes of a Holy God.

2. The Typological-Prophetic Nature

The sacrifices were more than just religious ceremonies; they were "Gospel in the Law."

2.1 The Messiah Replaces the Shadows

Psalm 40:6-8 presents a prophetic dialogue where the Messiah declares that God did not find ultimate delight in animal sacrifices, but in the perfect obedience of a body prepared for Him. Hebrews 10:5-9 interprets this as the moment the "shadows" retire because the "Reality" has arrived.

2.2 New Testament Confirmation

    • Colossians 2:17: Rituals are a "shadow of the things that were to come; the reality, however, is found in Christ."

    • John 1:29: John the Baptist identifies Jesus not as a philosopher, but as the "Lamb of God."

    • 1 Corinthians 5:7: Paul identifies Christ as "our Passover lamb."

Just as the bronze serpent was lifted in the wilderness to bring physical healing (John 3:14-15), Christ was lifted on the Cross to bring spiritual restoration.

3. The Purpose of Old Testament Sacrifices

These sacrifices functioned on two distinct levels:

3.1 The Theocratic Purpose (External)

Within the national covenant of Israel, sacrifices restored the offender to the community. They removed "ceremonial uncleanness" and allowed the person to participate in the external privileges of the nation.

3.2 The Spiritual Purpose (Typical)

In and of themselves, animal sacrifices had a limitation:

    • Hebrews 10:4: "It is impossible for the blood of bulls and goats to take away sins."

    • Hebrews 9:9: They could not "perfect the conscience" of the worshiper.

      Their value was prospective; they were valid only when accompanied by true repentance and faith in the coming Redeemer that God had promised.

4. Christ: Both Priest and Sacrifice

In the Old Testament system, the Priest and the Victim were always separate. In the New Covenant, they converge in one Person.

4.1 The Testimony of Hebrews

The Epistle to the Hebrews presents Christ as the Great High Priest who is:

    • Eternal: He does not die, so His priesthood never ends.

    • Perfect: He has no sin of His own to atone for.

    • Superior: His priesthood is according to the order of Melchizedek, surpassing the Aaronic/Levitical order.

    • Hebrews 9:12: He entered the Most Holy Place once for all by His own blood.

4.2 Apostolic and Christological Witness

    • Paul (Romans 3:24-25): God presented Christ as a sacrifice of atonement (propitiation).

    • Peter (1 Peter 3:18): "For Christ also suffered once for sins, the righteous for the unrighteous."

    • Jesus Himself (Mark 10:45): He came to "give his life as a ransom for many."

5. The Priestly Office in Modern Theology

Modernist theology often tries to minimize Christ’s offices, preferring to see Him only as a Prophet (a moral teacher or social reformer). They often reject His Sacerdotal (Priestly) Office, viewing the language of "blood" and "sacrifice" as outdated metaphors.

However, Scripture is adamant:

    • Christ is not a "metaphorical" priest. He is a real Priest, appointed by a divine oath.

    • Hebrews 7 argues that if His priesthood isn't real, our salvation isn't real.

    • When God declared, "You are a priest forever," He established an eternal, functional office that secures our access to the throne of grace today.

Conclusion

The Old Testament sacrifices were the "kindergarten" of the Gospel, teaching humanity the vocabulary of holiness, sin, death, and substitution. When we look at the smoke rising from the ancient altars, we are seeing a prophetic finger pointing toward Calvary. In Christ, the priest, the altar, and the lamb become one, providing a salvation that animal blood could never achieve.

4 proofs that Christ's work is complete:

I. His Mission of Redemption is Complete (John 19:30)

Our first proof lies in the words uttered by Jesus on the cross, "It is finished" (John 19:30). These three words encapsulate the essence of Christ's mission. He came into this world to redeem humanity from the bondage of sin and reconcile us with the Father. Through His sacrificial death and victorious resurrection, Jesus accomplished the full payment for our sins. He fulfilled the demands of justice, making a way for us to be reconciled to God and receive eternal life. In Christ's completion of this mission, we find hope, forgiveness, and everlasting salvation.

II. His Authority is Complete (Matthew 28:19-20; Hebrews 12:25)

The second proof of Christ's completeness lies in His authority. After His resurrection, Jesus appeared to His disciples and declared, "All authority in heaven and on earth has been given to me" (Matthew 28:18). With these words, He affirmed His supreme sovereignty over all creation. As believers, we are commissioned to make disciples of all nations, baptizing them in the name of the Father, Son, and Holy Spirit. The authority Christ bestowed upon us is rooted in His own authority. Furthermore, the book of Hebrews reminds us not to reject the voice of the One who speaks from heaven, emphasizing the fullness of Christ's authority and our responsibility to heed His teachings.

III. His Revelation is Complete (Jude 3; Hebrews 1:1-3)

The third proof of Christ's completeness lies in His revelation to us. Jude exhorts believers to contend for the faith that was once for all delivered to the saints (Jude 3). In the opening verses of the book of Hebrews, we learn that in the past, God spoke to His people through various prophets, but in these last days, He has spoken to us by His Son (Hebrews 1:1-2). Jesus Christ is the ultimate and complete revelation of God. He is the Word made flesh, the embodiment of divine truth and wisdom. Through His life, teachings, death, and resurrection, Christ has unveiled God's plan of salvation for all humanity. In Jesus, we find the fullness of God's revelation to us.

IV. His Glory is Complete (Luke 24:25-26; 1 Peter 1:20-21)

Our fourth and final proof of Christ's completeness lies in His glory. In Luke's Gospel, we read about the encounter between Jesus and the disciples on the road to Emmaus. Jesus, in His resurrected form, explained to them how all the Scriptures pointed to Him. He revealed the glory of His redemptive work, demonstrating that it was necessary for the Messiah to suffer and then enter into His glory (Luke 24:25-26). Additionally, in his epistle, Peter emphasizes that Jesus Christ was foreknown before the foundation of the world and was revealed in these last times for our sake (1 Peter 1:20-21). The glory of Christ's work shines brightly, illuminating the path of salvation and giving us assurance that He has accomplished all that was necessary for our redemption.

Conclusion:

As we reflect on these four proofs, we are reminded of the completeness of Christ's work. He fulfilled His mission of redemption, secured His authority, revealed God's plan fully, and manifested His glory. Let us rejoice in the knowledge that in Christ, we have received the ultimate gift—a complete and perfect salvation. May this understanding deepen our faith, inspire our worship, and motivate us to share the good news with others. May we always live in the joy and freedom that comes from knowing that Christ's work is indeed complete.
