Thayer's Greek Lexicon
STRONGS NT 981: βίωσις

βίωσις, βιώσεως, , manner of living and acting, way of life: Acts 26:4. (Sir. prolog. 10 διά τῆς ἐννόμου βιώσεως; not found in secular authors.)

Topical Lexicon
Word in Context

βίωσις appears once in the Greek New Testament—Acts 26:4—where Paul tells King Agrippa, “Surely all the Jews know how I have lived from youth, from the beginning among my own nation and in Jerusalem”. The noun refers to one’s manner of life, the observable pattern of conduct shaped by convictions and circumstances.

Historical Setting in Acts 26

Paul stands before Agrippa II and the Roman governor Festus, giving his final recorded defense before journeying to Rome. By invoking his “way of life” from childhood, Paul strategically roots his testimony in facts verifiable by his opponents. His use of βίωσις affirms:

1. Continuity—his past and present lives are open to scrutiny.
2. Credibility—public knowledge of his former Pharisaic zeal underscores the authenticity of his conversion.
3. Accountability—Paul’s whole life account stands as evidence that the gospel he preaches produces real transformation.

Connection to Other New Testament Motifs of Life

1. βίωσις (manner of life) focuses on outward, social existence.
2. βίος (livelihood, worldly life) speaks of material resources or temporal span (Luke 8:14; 1 John 2:16).
3. ζωή (life in its fullest sense) conveys God-given, eternal life (John 1:4; 3:16).

Paul’s speech moves from βίωσις (observable conduct) to ζωή (resurrection life in Christ) as he recounts the risen Lord’s commission (Acts 26:22–23).

Old Testament Resonance

Hebrew wisdom frequently links righteous “walk” with authentic faith (Psalm 1:1; Micah 6:8). Paul’s appeal to his βίωσις mirrors that heritage: a godly life validates the message (compare Proverbs 20:7).

Doctrinal Significance

1. Integrity of Witness—Believers are called to live “in a manner worthy of the gospel of Christ” (Philippians 1:27), so that conduct corroborates confession.
2. Transformation—Paul’s changed βίωσις illustrates regeneration (2 Corinthians 5:17).
3. Accountability Before Unbelievers—Transparent living silences accusation and adorns the doctrine of God (1 Peter 2:12; Titus 2:10).

Pastoral and Ministry Applications

• Testimony Development: Encourage believers to trace and share God’s work through their own βίωσις, as Paul did.
• Discipleship: Instruct new converts that Christian growth encompasses both inward faith and outward lifestyle (Ephesians 4:22–24).
• Leadership Qualification: Elders must have a blameless βίωσις, “above reproach” (1 Timothy 3:2), demonstrating the gospel’s power.
• Apologetics: A consistent life remains a compelling defense when engaging skeptics, echoing Paul’s method before Agrippa.

Summary

Though βίωσις occurs only once, it captures a vital biblical theme: the believer’s public conduct must square with the truth of the gospel. Paul’s appeal to his lifelong pattern of living challenges the church in every age to let its manner of life confirm, rather than contradict, the message of salvation in Jesus Christ.
