Luke 5:21: Jesus' authority questioned?
How does Luke 5:21 challenge our understanding of Jesus' authority to forgive sins?

Setting the Scene

Luke 5:21: “But the scribes and Pharisees began thinking to themselves, ‘Who is this man who speaks blasphemy? Who can forgive sins but God alone?’”

• Jesus has just pronounced forgiveness over the paralyzed man (v. 20).

• The religious experts recognize that forgiveness of sins is exclusively God’s prerogative (cf. Isaiah 43:25).

• Their silent objection frames the core issue: if Jesus is not God, His words are blasphemous; if He is God, His authority is absolute.


What the Scribes and Pharisees Understood

• The Law taught that sin is an offense against God (Psalm 51:4). Therefore, only God can pardon.

• Every Levitical sacrifice pointed to divine forgiveness mediated through the priesthood, never pronounced directly by a man on his own authority.

• By claiming to forgive instantly and personally, Jesus bypassed the whole sacrificial system, asserting prerogatives reserved for Yahweh.


Jesus’ Authority Unveiled

• He proves His right to forgive by healing the paralytic (Luke 5:24-25), providing visible confirmation of an invisible act.

• Parallel account: “The Son of Man has authority on earth to forgive sins” (Mark 2:10). The miracle validates the claim.

Daniel 7:13-14 identifies the “Son of Man” as the divine figure who receives everlasting dominion. Jesus links Himself to that prophecy.

• Later, He seals this authority through His atoning death and resurrection (Romans 4:25).


Theological Significance

• Deity of Christ: The episode forces a decision—either Jesus is God in flesh (John 1:14) or a blasphemer. Scripture presents Him unequivocally as God (John 20:28; Colossians 2:9).

• Substitutionary atonement foreshadowed: by forgiving before the cross, Jesus displays sovereign grace grounded in the sacrifice He would soon offer (Hebrews 10:10-14).

• Fulfillment of covenant promises: God promised a new covenant of full forgiveness (Jeremiah 31:34). Jesus inaugurates that reality.


Personal Application

• Confidence in forgiveness: Because Jesus possesses divine authority, believers rest in complete pardon (1 John 1:9).

• Worship and obedience: Recognizing His deity compels wholehearted devotion (Philippians 2:9-11).

• Evangelistic urgency: The same Lord who forgives also commands the gospel proclamation (Luke 24:47).
