Ephesians 6:10 from the King James Version (KJV) of the Bible says, "Finally, my brethren, be strong in the Lord, and in the power of his might." This verse is part of a larger passage in the book of Ephesians that deals with spiritual warfare and the armor of God. In this verse, the apostle Paul exhorts believers to be strong in the Lord and in the power of His might, emphasizing the need for spiritual strength and reliance on God in the face of spiritual battles and challenges.

The book of Ephesians was written by the apostle Paul during his imprisonment in Rome, around A.D. 60-61. It was written to the church in Ephesus, along with other churches in the region of Asia Minor. The letter addresses various theological and practical aspects of the Christian faith, including the unity of believers in Christ, the nature of the church, and the Christian's walk in the world.

In the larger context of Ephesians 6, Paul uses the imagery of a soldier in battle to illustrate the spiritual warfare that believers face. He urges believers to put on the whole armor of God in order to stand firm against the schemes of the devil. The armor of God includes the belt of truth, the breastplate of righteousness, the shoes of the gospel of peace, the shield of faith, the helmet of salvation, and the sword of the Spirit, which is the word of God. Each piece of the armor is symbolic of a spiritual truth or attribute that is essential for the believer's protection and effectiveness in spiritual warfare.

In verse 10, Paul begins his exhortation by emphasizing the necessity of being strong in the Lord and in the power of His might. The phrase "be strong" is a call to spiritual fortitude and endurance, which can only be achieved through a deep and abiding relationship with the Lord. The strength that Paul speaks of is not merely human strength, but the supernatural strength that comes from God. This strength is derived from a close and dependent relationship with Him, and it enables believers to withstand the attacks of the enemy and to remain firm in their faith in the face of trials and temptations.

The phrase "in the Lord" emphasizes the source of this strength. Believers are not to rely on their own abilities or resources, but to draw upon the limitless power of God. This power is made available to believers through their union with Christ and the indwelling of the Holy Spirit. As they submit to the Lord and walk in obedience to His will, they are able to tap into the divine strength that is sufficient for all their needs.

The phrase "power of his might" further emphasizes the supernatural nature of the strength that believers are called to rely on. The word "power" (Greek: kratos) refers to dominion, might, and strength, while the word "might" (Greek: ischus) conveys the idea of force, ability, and capability. Together, these words underscore the idea of God's limitless and invincible power, which is available to believers as they engage in spiritual warfare.

The theme of strength in the Lord is a recurring one in the Bible. Throughout Scripture, believers are encouraged to rely on God's strength rather than their own. Psalm 28:7 says, "The Lord is my strength and my shield; my heart trusts in him, and he helps me." Isaiah 40:29 declares, "He gives strength to the weary and increases the power of the weak." 2 Corinthians 12:9 reminds us that God's power is made perfect in our weakness. These and other verses affirm the truth that true strength comes from God alone.

In conclusion, Ephesians 6:10 is a powerful reminder of the importance of drawing strength from the Lord in the midst of spiritual battles. Believers are called to rely on God's supernatural power and might, rather than their own human resources. This verse encourages us to cultivate a deep and abiding relationship with the Lord, through which we can access His inexhaustible strength and be equipped to stand firm in the face of spiritual opposition. As we put on the whole armor of God and stand in His strength, we can be assured of victory in the spiritual battles that we face.
