Topical Lexicon
Overview

Strong’s Greek 3167 describes the “mighty deeds” or “great things” that testify to God’s matchless power and majesty. The single New Testament occurrence appears at the birth-of-the-Church event in Acts 2:11, where Spirit-filled disciples declare “the magnificent works of God” (μεγαλεῖα τοῦ Θεοῦ).

Pentecost and the First Use

Acts 2 records Jews and proselytes from every nation hearing the gospel in their own languages. Among the many dialects represented, the common theme was not personal experience but God’s own exploits:

“Cretans and Arabs—we hear them declaring the magnificent works of God in our own tongues!” (Acts 2:11).

The Spirit’s inaugural sermon thus centers on divine achievement rather than human eloquence. The term signals that salvation history has reached its apex in the death, resurrection, and exaltation of Jesus Christ, now proclaimed to the nations.

Old Testament Backdrop: Proclaiming His Mighty Acts

Although the exact Greek term is unique to Acts, the idea pervades Scripture. Repeatedly Israel is charged to recount God’s wonders:
Deuteronomy 11:2 – Israel must remember “His greatness, His mighty hand, and His outstretched arm.”
Psalm 145:4-6 – “One generation will proclaim Your works to the next and will declare Your mighty acts.”
Isaiah 63:7 – The prophet recalls “the loving devotion of the LORD” and “His great goodness.”

Luke, a Septuagint-steeped historian, deliberately invokes this heritage. The outpoured Spirit empowers a renewed people to continue the age-old vocation of publishing God’s covenant faithfulness, now climaxed in Christ.

Christological Focus

The “mighty deeds” ultimately converge on the Person and work of Jesus: His incarnation (John 1:14), miracles (Acts 10:38), sin-bearing death (1 Peter 2:24), resurrection (Romans 1:4), and kingly exaltation (Philippians 2:9-11). Peter’s Pentecost sermon (Acts 2:22-36) immediately follows the crowd’s hearing of these deeds, tying the vocabulary to the gospel narrative itself.

Trinitarian Dynamic

• God the Father authors the plan of redemption (“the determined plan and foreknowledge of God,” Acts 2:23).
• God the Son accomplishes the mighty work through the cross and empty tomb.
• God the Spirit applies and broadcasts the finished work, enabling human witnesses to articulate it in every tongue.

Missionary Implications

Pentecost models Spirit-empowered proclamation that is:

1. God-centered—focusing on what He has done.
2. Multilingual—accessible to every people group.
3. Scripture-saturated—interpreting present experience by the written Word.

Modern missions mirror this pattern: herald the gospel’s mighty acts, trust the Spirit to bridge linguistic and cultural divides, and base all teaching on Scripture’s authority.

Worship and Doxology

The term invites corporate praise. Biblical worship is less about subjective feeling than objective reality—God’s historical interventions. Whether in ancient Israel, a Jerusalem upper room, or a twenty-first-century congregation, God’s people assemble to declare His μεγαλεῖα. Traditional hymns (“Great Is Thy Faithfulness”) and contemporary songs alike stand in continuity with Pentecost when they rehearse God’s acts of creation, providence, redemption, and consummation.

Pastoral Application

• Testimony: Personal accounts gain weight when tethered to God’s mighty deeds in Christ.
• Catechesis: Discipleship should familiarize believers with the sweep of redemptive history, anchoring faith in God’s acts rather than fleeting experience.
• Encouragement: Reminding saints of God’s past greatness fosters present trust (Psalm 77:11-14).

Eschatological Anticipation

Pentecost previews a universal confession yet to come. Revelation envisions every tribe and language praising the Lamb for His mighty salvation (Revelation 7:9-10). The singular use of the term hints that the final chorus will be a seamless continuation of the first Spirit-given doxology.

Conclusion

Though Strong’s Greek 3167 appears only once, it encapsulates the heartbeat of Scripture: God reveals Himself through mighty deeds, culminating in Jesus Christ, and the Spirit commissions the Church to proclaim these deeds to all nations until He comes.
