Hebrews 9:17

For a Testament is of force after men are dead: otherwise it is of no strength at all whilest the Testatour liueth. Hebrews 9:17 (KJV)

For where a testament is, there must also of necessity be the death of the testator.

Context and Background: The book of Hebrews was written to Jewish Christians who were facing persecution and considering returning to Judaism. The author of Hebrews presents Jesus Christ as the fulfillment of the Old Testament prophecies and the superior High Priest who brings a better covenant. Hebrews 9 discusses the contrast between the Old Covenant, characterized by the sacrificial system and the tabernacle, and the New Covenant established through Jesus’ sacrifice.

The Mediator of the New Covenant: In Hebrews 9:15, the author refers to Jesus Christ as the “mediator of the new covenant” (or “testament” in some translations). A mediator is a go‑between, someone who brings parties together, reconciles differences, and establishes an agreement. Jesus is the mediator of the New Covenant between God and humanity. Through His sacrificial death on the cross, He made it possible for people to enter into a new relationship with God.

The Purpose of Jesus’ Death: The verse states that Jesus became the mediator of the New Covenant “by means of death.” Jesus’ death on the cross was central to the establishment of the New Covenant. His death served as a sacrificial offering for the redemption of sins committed under the Old Covenant. The Old Testament sacrificial system provided temporary atonement for sins, but Jesus’ sacrifice was once‑for‑all, completely and permanently removing the transgressions of those who believe in Him.

Redemption of Transgressions: The author emphasizes that Jesus’ death provided redemption for the transgressions committed under the first testament (Old Covenant). The Old Covenant, represented by the Mosaic Law, revealed humanity’s inability to fully obey and find forgiveness through their own efforts. The blood of animal sacrifices could not cleanse the conscience of the people permanently. However, Jesus’ sacrifice offered a final and perfect redemption, freeing believers from the guilt and power of sin.

The Promise of Eternal Inheritance: The ultimate result of Jesus’ sacrificial death is that those who are called (believers) receive the promise of “eternal inheritance.” Under the Old Covenant, inheritance was connected to the land of Canaan and earthly blessings. Through Jesus, believers are offered an eternal inheritance in the kingdom of God—eternal life, fellowship with God, and the fullness of His promises, an inheritance that cannot fade, spoil, or be taken away (1 Peter 1:4).
