Topical Lexicon
Astonishment in the Presence of Divine Power

The adjective ἔκθαμβος (ekthambos) depicts a visceral reaction of awe that overwhelms the senses when people encounter the living God at work. It conveys more than curiosity; it is the stunned awareness that the human realm has been interrupted by heaven’s authority.

The Single New Testament Occurrence

Acts 3:11 records the immediate aftermath of the healing of the man lame from birth: “While the man clung to Peter and John, all the people were astonished and ran to them in the portico called Solomon’s”. Luke’s use of ἔκθαμβοι highlights three realities:

1. The miracle was undeniable; the healed man stood as living evidence.
2. The crowd’s amazement sprang not merely from the event but from its God-centered explanation (Acts 3:12-16).
3. The astonishment created an open door for apostolic preaching that called Israel to repentance (Acts 3:19).

Awe as a Divine Catalyst

Scripture often pairs amazement with revelation (Exodus 15:11; Psalm 65:8; Luke 5:26). In Acts 3, astonishment functions as a catalyst that moves the crowd from spectacle to sermon. Peter redirects their wonder, insisting that the miracle exalts “the God of Abraham, Isaac, and Jacob, the God of our fathers” (Acts 3:13), displaying the continuity of God’s covenant faithfulness.

Historical Significance in Acts

This episode occurs at the temple, the heart of Jewish worship. By manifesting Christ’s healing power in Solomon’s Portico—the very precinct where Jesus Himself had once taught (John 10:23)—the risen Lord validates His messianic identity before Israel’s gathered pilgrims. The crowd’s amazement therefore bridges Jesus’ earthly ministry and the church’s Spirit-empowered witness.

Ministry Implications

1. Expectation of Manifest Power. The church today proclaims a Savior who remains able to astonish (Hebrews 13:8).
2. Stewardship of Wonder. Spiritual leaders must imitate Peter by turning public fascination toward repentance and faith rather than personal acclaim (Acts 3:12).
3. Apologetic Value. Genuine works of God arrest attention, preparing hearts for the gospel (John 9:30-33; Acts 4:14-16).
4. Corporate Worship. Awe is integral to healthy Christian assembly (Acts 2:43). Believers are to preserve reverence while avoiding sensationalism (1 Corinthians 14:40).

Old Testament Roots of Holy Astonishment

Moses trembled at the burning bush (Exodus 3:6). Israel feared exceedingly at Sinai (Exodus 20:18-21). These narratives foreshadow the temple-crowd’s reaction in Acts 3 and affirm that true encounters with God consistently evoke profound awe.

Christ-Centered Fulfillment

The healed beggar’s restored legs echo prophetic promises that “the lame will leap like a deer” (Isaiah 35:6). The crowd’s astonishment therefore testifies that messianic times have dawned through Jesus Christ, fulfilling and surpassing earlier revelations.

Personal Application

Believers are summoned to cultivate a heart that remains “astonished” at the grace of God (Romans 11:33-36). Such reverent wonder fuels worship, deepens humility, and propels evangelism.

Summary

Ἔκθαμβος portrays a moment when human faculties are overpowered by divine reality. Its lone appearance in Acts 3:11 crystallizes the New Testament pattern: God acts, people are astonished, and the gospel is proclaimed. The church is called to steward that same holy amazement for the glory of Jesus Christ.
