Ephesians 6:10 gives a clear, steady encouragement: Your strength for spiritual battles does not come from you — it comes from the Lord Himself.

The verse says:

“Finally, be strong in the Lord and in the strength of His might.”

Here’s the encouragement wrapped inside that command:

1. God does not ask you to be strong on your own

Paul doesn’t say, “Be strong.” He says, “Be strong in the Lord.” Your strength is borrowed — and God never runs out.

2. God’s strength is greater than your weakness

“The strength of His might” means:

• His power is enough for your pressures
• His endurance is enough for your fatigue
• His courage is enough for your fears
• His victory is enough for your battles

You stand in His ability, not yours.

3. You are not fighting alone

This verse begins the Armor of God passage. Before Paul describes any armor, he reminds you of the most important truth:

God Himself is your strength.

You don’t enter spiritual conflict unprotected or unsupported.

4. Strength grows from relationship, not effort

You become strong by staying close to Him, not by trying harder. His presence produces your stability.

Encouragement in one line

Ephesians 6:10 assures you that God supplies the strength you need for every battle you face — you stand in His power, not your own.

Finally, be strong in the Lord and in the strength of his might. (Ephesians 6:10 ESV)

Looking back to Ephesians 4 and starting at verse 17, Paul speaks of the new life we have in Jesus Christ and then begins to describe what that life should look like. After listing many characteristics, we come to chapter 5, where he then speaks of the importance of walking in love as children of light. He then focuses on husbands and wives and how they should relate. Chapter 6 begins with a focus on children and parents and then we come to “Finally” of verse 6:10 as Paul draws near the end of his letter to the church at Ephesus.

Verse 10 opens the final section of instruction with the command to “be strong in the Lord and in the strength of his might.” Some translations replace “strong” with “strengthened” with other words or phrases being used in some translations and paraphrases. To be strong in the Lord is to be strong in our faith (Romans 4:20). It is a strength that comes by the grace that is in Christ Jesus (2 Timothy 2:1). We are strengthened in our inner being according to the riches of his glory (Ephesians 3:16).

Why do we need this strength? We need to be strengthened to be able to stand against superhuman powers that come against us. As believers, we are caught in the struggle that is being waged between good and evil; between light and darkness. “We do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places,” (Ephesians 6:12 ESV) and for this we need to be strengthened.

This strength is expressed in verse 1:19 in terms of “the immeasurable greatness of his power toward us who believe.” We are to surrender our own strength through being crucified with Christ and yield our lives to him and allow him to live in us, and as we live in the flesh by faith in the Son of God, his might becomes the strength in which we endure and overcome the evil and the spiritual darkness that is arrayed against us.

Father thank you that “The Lord is my rock and my fortress and my deliverer, my God, my rock, in whom I take refuge, my shield, and the horn of my salvation, my stronghold” (Psalm 18:2 ESV). Who is thus able to overcome us? No one for the victory is ours in him. “My flesh and my heart may fail, but God is the strength of my heart and my portion forever. (Psalm 73:26 ESV) Amen!

Ephesians 6:10 (ESV)

“Finally, be strong in the Lord and in the strength of his might.”

Discussion Questions with Extended Answers

1. What does Paul mean when he tells believers to “be strong in the Lord”?

Answer:
Paul is not commanding believers to rely on their own determination, personality, intelligence, or personal abilities. The phrase “be strong in the Lord” means that spiritual strength comes from God Himself. The believer’s ability to stand firm against temptation, discouragement, fear, and spiritual opposition is not produced by human effort alone but by dependence upon God’s power.

This command appears at the beginning of Paul’s teaching about the armor of God (Ephesians 6:10–18). Before describing the belt of truth, breastplate of righteousness, shield of faith, and other spiritual weapons, Paul establishes the foundation: victory comes from God’s strength. A believer cannot successfully fight spiritual battles by human strength but must continually draw from the Lord.

The Christian life requires humility because recognizing our weakness opens the way for God’s power to work through us. As Paul wrote in 2 Corinthians 12:9, God’s power is made perfect in weakness. Being strong in the Lord means trusting that God provides everything necessary to remain faithful.

2. Why does Paul emphasize “the strength of his might” rather than the believer’s own strength?

Answer:
Paul emphasizes God’s might because spiritual battles are greater than human ability. The struggles believers face are not merely against difficult circumstances or human opposition but against spiritual forces that require divine power (Ephesians 6:12).

The phrase “the strength of his might” points to God’s unlimited power. Throughout Scripture, God’s might is demonstrated through creation, deliverance, resurrection, and His sustaining care for His people. The same power that raised Christ from the dead is available to strengthen believers in their daily walk.

Human strength is limited and temporary. A person may have knowledge, discipline, courage, or resources, but none of these alone can overcome spiritual deception or temptation. God’s strength provides endurance, wisdom, faith, and perseverance.

Therefore, Paul directs believers away from self-confidence and toward God-confidence. The Christian does not stand because he or she is strong but because God is strong.

3. How can believers practically “be strong in the Lord” in everyday life?

Answer:
Believers become strong in the Lord by developing a life of dependence upon God through spiritual practices and obedience. This includes prayer, studying and applying God’s Word, worship, fellowship with other believers, and trusting God’s promises.

Being strong in the Lord means beginning each day with the awareness that we need God’s guidance and power. It means bringing decisions, struggles, fears, and temptations before Him rather than attempting to handle everything independently.

Practical examples include:

• Prayer: Seeking God’s help rather than relying only on personal solutions.
• Scripture: Allowing God’s truth to shape our thinking and protect us from deception.
• Faith: Trusting God when circumstances are difficult or uncertain.
• Obedience: Following God’s commands even when obedience requires sacrifice.
• Perseverance: Continuing faithfully because God provides strength.

Spiritual strength grows as believers repeatedly depend on God rather than themselves.

4. What does Ephesians 6:10 teach about the source of spiritual victory?

Answer:
Ephesians 6:10 teaches that spiritual victory begins with God, not with human ability. Before Paul discusses the armor of God, he reminds believers that their preparation must begin with the Lord’s power.

This verse changes the way believers view spiritual challenges. The question is not, “Do I have enough strength?” but rather, “Am I relying on God’s strength?” Victory comes when believers remain connected to the One who has already overcome sin, death, and Satan through Jesus Christ.

The believer’s role is not to create spiritual power but to receive and use the strength God provides. God equips His people with everything necessary to stand firm.

This verse also gives encouragement because it means believers are never facing spiritual battles alone. The Lord’s strength is greater than any opposition they encounter.

5. How should Ephesians 6:10 encourage believers who feel weak or inadequate?

Answer:
Ephesians 6:10 provides hope because it acknowledges that believers are not naturally strong enough for every challenge they face. God does not command believers to be strong in themselves; He commands them to be strong in Him.

Feelings of weakness, uncertainty, or inadequacy can become reminders to seek God’s strength. The believer’s confidence rests not in personal perfection but in God’s faithfulness.

Throughout Scripture, God used people who recognized their weakness:

• Moses felt inadequate to lead Israel.
• Gideon considered himself insignificant.
• David faced enemies far greater than himself.
• The disciples often lacked understanding and courage.

Yet God strengthened them for His purposes.

Ephesians 6:10 reminds believers that God does not call them to accomplish His work through their own strength. He calls them to trust Him and allow His power to work through them.

Summary Truth:

Spiritual strength does not come from within ourselves but from the Lord who supplies the power needed to stand firm. The believer’s victory is found not in human ability but in dependence upon God’s mighty strength.
