Topical Lexicon
Overview of the Verb’s Theme

Strong’s Greek 1743 portrays God-given empowerment that enables believers to fulfill divine purposes. In every occurrence the strengthening comes from the Lord, never from human resolve alone, and it results in effective witness, endurance, or obedience.

Occurrences in the New Testament

1. Acts 9:22 – Saul “grew more powerful,” refuting opponents by proving Jesus is the Christ.
2. Romans 4:20 – Abraham “was strengthened in his faith,” glorifying God despite impossible circumstances.
3. Ephesians 6:10 – “Be strong in the Lord and in His mighty power,” the doorway to the armor of God.
4. Philippians 4:13 – “I can do all things through Christ who gives me strength,” personal sufficiency rooted in union with Christ.
5. 1 Timothy 1:12 – Paul thanks Christ Jesus “who has strengthened me,” grounding his apostolic call.
6. 2 Timothy 2:1 – “Be strong in the grace that is in Christ Jesus,” Timothy’s charge for generational discipleship.
7. 2 Timothy 4:17 – “The Lord stood by me and strengthened me,” ensuring the gospel reached the nations.

Divine Source of Empowerment

The strengthening is consistently attributed to God the Father, Jesus Christ, or grace itself. Human weakness becomes the canvas on which divine power is displayed (compare 2 Corinthians 12:9). Thus empowerment is relational rather than merely mechanical, flowing from fellowship with the Lord.

Christological Focus

Philippians 4:13 and 1 Timothy 1:12 explicitly link strength to Christ. In Acts 9:22 Saul’s newfound power arises from his encounter with the risen Jesus. The verb underscores that all Christian vigor is Christ-derived; the believer is the vessel, Christ the empowering presence.

Ministry Application

Paul’s letters show that authentic ministry is impossible without divine strengthening. Timothy is told to draw strength from grace because pastoral labor—entrusting truth to “faithful men” (2 Timothy 2:2)—demands more than natural ability. Likewise, Paul’s standing trial in 2 Timothy 4:17 illustrates that the Lord’s empowering secures gospel proclamation even in hostile courts.

Spiritual Warfare and Armor

Ephesians 6:10 sets the keynote for the armor passage. The imperative “be strong” is passive-middle in force: believers are commanded to receive strength. The ensuing armor pieces describe how divine empowerment is appropriated—truth, righteousness, faith, salvation, Word, and prayer. Victory in spiritual conflict is thereby located in God’s might, not human schemes.

Perseverance in Suffering

Whether Abraham awaiting a promised son (Romans 4:20) or Paul abandoned at trial (2 Timothy 4:17), empowerment undergirds endurance. Strength is not an escape from hardship but the capacity to glorify God within it. The verb thus bridges Old and New Testament testimony; Abraham’s example mirrors Isaiah 40:29–31, where the Lord “gives power to the faint.”

Faith and Empowerment

Romans 4 links strengthening to faith’s enlargement. Empowerment both fuels and is fueled by trust in God’s promises. As faith praises God in advance, inner vigor increases, forming a virtuous cycle of belief and power.

Early Church Witness

Acts 9:22 shows that empowerment translated into persuasive proclamation. Patristic writers echoed this theme: Ignatius of Antioch urged believers to “be strengthened in the faith” (Letter to the Trallians 12), reflecting the same verb family. The early church understood that bold witness required supernatural enablement.

Practical Exhortation for Believers Today

• Seek strength through intimate communion with Christ (Philippians 4:13).
• Rely on grace, not self-reliance, for ministry tasks (2 Timothy 2:1).
• Arm yourself daily with gospel truths, recognizing that empowerment and armor are inseparable (Ephesians 6:10–18).
• Expect divine strength to manifest amid weakness and opposition (2 Timothy 4:17).
• Praise God in the waiting, trusting Him to fortify faith as He did for Abraham (Romans 4:20).
