Why doesn't God repay our sins?
Why does God not repay us according to our sins, as stated in Psalm 103:10?

Canonical Placement and Immediate Context

Psalm 103 sits among the Davidic psalms of Book IV (Psalm 90–106), a section highlighting God’s sovereign mercy after Israel’s exile anxieties. Verse 10—“He has not dealt with us according to our sins, nor repaid us according to our iniquities” —is embedded in a hymn that traces salvation history from personal forgiveness (vv. 1–5) to national covenant faithfulness (vv. 6–18) and cosmic lordship (vv. 19–22). It therefore speaks to individual, communal, and universal dimensions of grace.


Vocabulary of Unmerited Mercy

“Dealt” (גָּמַל, gamal) carries the idea of recompense; “sins” (חַטָּאָה, ḥaṭṭāʾâ) and “iniquities” (עָוֺן, ʿāwōn) denote willful deviation and guilt-laden perversity. What is withheld is strict lex talionis justice. The following verse grounds the negation in God’s “loving devotion” (חֶסֶד, ḥesed)—a covenant term connoting steadfast, promise-rooted love rather than mere sentiment.


Covenant Framework: Exodus Echoes

Psalm 103:8 quotes Exodus 34:6 verbatim, linking David’s worship to Yahweh’s self-revelation after the golden-calf rebellion. Israel had forfeited favour; yet God proclaimed Himself “compassionate and gracious.” Thus Psalm 103:10 recasts the Sinai narrative: because atonement was mediated through blood (Exodus 34:25; Leviticus 17:11) God withheld deserved wrath.


Sacrificial Typology: Substitution Prefigured

Under the Mosaic system, the sinner’s guilt was symbolically transferred to a flawless animal (Leviticus 1–7, 16). Hebrews 9:22 interprets this as a “copy and shadow” anticipating Christ’s self-offering. Psalm 103:10 therefore gestures forward to a definitive substitute who would bear sin without the sinner’s extermination (Isaiah 53:5–6).


Christological Fulfilment: Atonement, Resurrection, and Vindication

1 Peter 2:24 echoes the psalm: “He Himself bore our sins in His body on the tree.” The empty tomb (Matthew 28:6) is divine receipt that the debt is fully cancelled (Romans 4:25). Historical minimal facts—attested by 1 Corinthians 15:3–8’s early creed, multiple independent appearances, and the disciples’ martyr-willing transformation—establish the resurrection as the objective ground for God’s non-repayment. Justice fell on Christ; mercy falls on believers (2 Corinthians 5:21).


Legal Doctrine: Imputation and Propitiation

“Repayment” presupposes moral accounts. Romans 3:25 calls Christ a “propitiation” (ἱλαστήριον, hilastērion) satisfying righteous wrath. Concurrently, His righteousness is “credited” (λογίζομαι, logizomai) to faith-receiving sinners (Romans 4:5). Divine forbearance in Psalm 103:10 is thus neither amnesia nor laxity but deferred judgment resolved at Calvary.


Psychological and Behavioral Transformation

Empirical studies on gratitude therapy echo Titus 2:11–12: grace “trains us” away from ungodliness. Knowing one will not be repaid according to sin produces secure attachment to God, lowering shame-driven rebellion and fostering altruism (cf. 2 Corinthians 5:14).


Theodicy: Justice and Mercy Reconciled

Skeptics pose Euthyphro-type dilemmas: can God be just if He pardons? Romans 3:26 answers: He is “just and the justifier” because the penalty is not ignored but transferred. Mercy does not negate justice; it satisfies it in another.


Parallel Scriptural Witnesses

Ezra 9:13—“Our God has punished us less than our iniquities deserve.”

Lamentations 3:22—“Because of the LORD’s loving devotion we are not consumed.”

Ephesians 2:4–5—“Because of His great love… by grace you have been saved.”

Consistent testimony across covenants affirms God’s character and method.


Pastoral Application

Receive: Trust Christ alone; do not self-atone (Acts 16:31).

Respond: “Fear the LORD… keep His commandments” (Psalm 103:17–18).

Reflect: Extend mercy to others (Matthew 18:33), mirroring God’s economy.


Answer in Summary

God withholds deserved recompense because His covenant loving devotion finds ultimate expression in the substitutionary, resurrection-verified sacrifice of Christ, fulfilling justice so mercy may freely flow to all who believe.
