Why must Son of Man suffer in Mark 9:12?
Why must the Son of Man suffer according to Mark 9:12?

Text Of Mark 9:12

“And He answered, ‘Elijah does indeed come first, and he restores all things. Yet how then is it written about the Son of Man that He must suffer many things and be rejected?’”


Immediate Literary Context

In Mark’s narrative, Jesus has just descended the Mount of Transfiguration (Mark 9:2–9). The disciples have seen His glory; now He re-anchors them in the path of suffering. Mark 8:31 has already introduced the “must” of His death, and Mark 9:31 and 10:33–34 will repeat it. The juxtaposition of unveiled glory and unavoidable suffering drives the question: why is suffering necessary for the Son of Man?


The Son Of Man: Prophetic Identity

“Son of Man” echoes Daniel 7:13–14 where the figure receives everlasting dominion. Mark presents Jesus as that exalted person, yet Daniel’s vision follows scenes of beastly oppression. The path to dominion runs through conflict and apparent defeat. By adopting the title, Jesus signals both regal authority and solidarity with afflicted humanity (Psalm 8:4).


Scriptural Foundations For A Suffering Messiah

Law: Genesis 3:15 introduces a Deliverer bruised in the heel while crushing the serpent’s head, establishing the redemptive pattern of wounded victory.

Prophets: Isaiah 52:13–53:12 foretells a Servant “despised and rejected… pierced for our transgressions” (Isaiah 53:3,5). The Great Isaiah Scroll (1QIsaa, c.125 BC) confirms the pre-Christian date and wording. Zechariah 12:10 predicts the piercing of Yahweh’s Shepherd.

Writings: Psalm 22 details mockery, pierced hands and feet, and divided garments—fulfilled verbatim at Calvary (Mark 15:24,29). Psalm 118:22 speaks of the stone the builders rejected becoming the cornerstone (quoted by Jesus, Mark 12:10).

Collectively, “it is written” (Mark 9:12) encapsulates this tri-fold witness.


The Theological Necessity: Divine Justice And Redemption

Romans 3:25–26 declares God set forth Christ “as a propitiation… to demonstrate His righteousness.” Sin incurs death (Genesis 2:17; Romans 6:23). A righteous God must judge; a loving God provides substitution. The incarnate Son, sharing Adamic flesh yet without sin (Hebrews 4:15), could bear humanity’s penalty. His suffering satisfies justice, displays mercy, and defeats the powers of darkness (Colossians 2:14–15).


Covenantal Fulfillment And Sacrificial Pattern

From Abel’s offering (Genesis 4:4) to the Passover lamb (Exodus 12) and Levitical sin offerings (Leviticus 16), blood-shedding secures atonement. Hebrews 10:1–10 states these shadows “could never by the same sacrifices… make perfect,” necessitating the once-for-all self-offering of Christ. The New Covenant promised in Jeremiah 31:31 is inaugurated by His blood (Mark 14:24).


Foreshadows And Typology In Israel’S History

Joseph suffers betrayal yet saves nations (Genesis 37–50). David, the anointed, endures rejection before enthronement (1 Samuel 19–31). These narratives prefigure Messianic humiliation preceding exaltation (Acts 2:30–33). The Bronze Serpent (Numbers 21:8-9; John 3:14) typifies the lifting up of Christ for healing.


The Restoration Motif: Elijah And The Son Of Man

Malachi 4:5 promises Elijah’s return “before the great and fearful day of the LORD.” Jesus identifies John the Baptist as that Elijah (Mark 9:13; cf. Matthew 11:14). John’s ministry of repentance aimed to “restore all things,” yet he was imprisoned and beheaded (Mark 6:17-29). If the forerunner faced suffering, the messianic fulfillment would logically involve greater suffering. Restoration of all things (Acts 3:21) ultimately requires the atoning death and resurrection of the Messiah (Acts 3:18).


THE DIVINE “MUST” (Greek dei) IN MARK AND THE NEW TESTAMENT

The verb dei denotes divine compulsion. Mark 8:31; 9:12,31; 10:45; 14:49 each employ it for Christ’s passion. Luke 24:26–27 reiterates, “Was it not necessary (dei) for the Christ to suffer these things and then to enter His glory?” The necessity is not mere fate but covenantal decree (Acts 2:23).


Pastoral And Discipleship Implications

Jesus links His suffering to the disciple’s path: “If anyone wants to follow Me, he must deny himself, take up his cross, and follow Me” (Mark 8:34). Suffering for righteousness becomes normative, yet suffused with hope because resurrection follows (1 Peter 4:13).


Summary

The Son of Man “must suffer” because Scripture foretold a redeeming, rejected Messiah; divine justice required a sinless substitute; covenant typology demanded sacrificial blood; restoration promised through Elijah’s ministry necessitated a greater fulfillment; and God’s sovereign plan (dei) ordained the pathway of suffering to glory. Mark 9:12 succinctly gathers these threads, revealing that without the suffering of the Son of Man there could be no atonement, no restoration, and no ultimate exaltation.
