Acts 20:21: Repentance & faith in Jesus?
What does Acts 20:21 reveal about the necessity of repentance and faith in Jesus?

Text Of Acts 20:21

“solemnly testifying to Jews and Greeks alike about repentance to God and faith in our Lord Jesus Christ.”


Immediate Literary Context

Paul’s farewell address to the Ephesian elders (Acts 20:17-38) is his only recorded speech aimed exclusively at believers. Verses 20-21 summarize his entire evangelistic message during three years in Ephesus (cf. Acts 19). He highlights not miracles, not ethics, but the twin pillars of “repentance to God” and “faith in our Lord Jesus Christ.”


Theological Necessity

1. Universal Requirement—Paul “testifies to Jews and Greeks alike,” echoing Romans 3:23-24; no ethnic or moral pedigree exempts anyone.

2. Two-Fold Response—Repentance addresses alienation from God; faith appropriates the provision in Christ (Mark 1:15).

3. Christ-Centered Exclusivity—Faith is directed “in our Lord Jesus Christ,” aligning with Jesus’ own claim (John 14:6) and apostolic proclamation (Acts 4:12).


Unity With The Rest Of Scripture

• Prophetic Continuity: Ezekiel 18:30-32 links repentance with life; Isaiah 55:6-7 calls sinners to return to Yahweh.

• Apostolic Harmony: Peter’s Pentecost sermon (Acts 2:38) and later statement (Acts 3:19) mirror the same pair.

• Pauline Consistency: Acts 26:18-20; Romans 1:5; 10:9-10; 2 Corinthians 7:10; 1 Thessalonians 1:9-10.


Historical And Manuscript Corroboration

Acts 20 is preserved in P74 (3rd cent.), Codex Vaticanus (4th), and Codex Sinaiticus (4th) with negligible variation, underscoring textual stability. Early patristic citations—e.g., Irenaeus, Against Heresies 3.14.2—quote the passage, showing 2nd-century recognition.


Universal Scope, Particular Object

While the call is global—“Jews and Greeks alike”—salvation’s object is singular: the crucified-and-risen Jesus (1 Corinthians 15:3-4). The historical resurrection, attested by multiple eyewitnesses (1 Corinthians 15:5-8) and investigated by modern scholarship, grounds the legitimacy of the faith demand (Acts 17:31).


Relation Of Repentance To Faith

Scripture sometimes emphasizes repentance (Luke 24:47), other times faith (John 3:16). Acts 20:21 binds them together: repentance turns from sin and false trusts; faith turns toward Christ. Two sides of one coin; neglect either and the gospel is truncated.


Practical Imperatives For The Church

• Evangelism: Present both elements; avoid prosperity promises or moralism alone.

• Discipleship: Ongoing repentance and faith characterize sanctification (Colossians 2:6-7).

• Worship: Repentance glorifies God’s holiness; faith magnifies His grace.


Common Objections Answered

• “Repentance is obsolete under grace.” Paul here, decades after Pentecost, still preaches it. Grace produces, not replaces, repentance (Titus 2:11-12).

• “Faith alone suffices; repentance adds works.” Faith without a turning heart is dead (James 2:17). Repentance is the inward pivot that enables authentic faith.

• “Different groups need different messages.” Paul declares one identical requirement for both cultural spheres.


Summary

Acts 20:21 distills the gospel demand: every person must repent toward God and believe in the risen Lord Jesus. This dual response is universally mandated, textually secure, theologically indispensable, historically grounded, and experientially verified.
