Finally, be strong in the Lord, and in the strength of his might.
This closing exhortation calls believers to find their endurance not in self-reliance but in union with the risen Christ. The phrasing echoes Old Testament images of divine power, yet now it is applied to every follower. Our daily struggles require a strength beyond human limits, which God provides through intimate connection with him.
Explanation
Historical and Cultural Context
Paul writes to a church in Ephesus, a city dominated by the cult of Artemis and pervasive magical practices, where people sought power through incantations and amulets. The phrase ‘in the Lord’ echoes the believer’s union with Christ, a theme woven throughout this letter. By calling for strength ‘in the strength of his might,’ Paul draws on Old Testament language to contrast the frailty of human devices with God’s inherent power. Written likely from Roman imprisonment, the letter shows that true might is found not in civic status or occult protection, but in the living Christ who has been exalted over every cosmic ruler.
Theological Explanation
This verse marks the transition from household duties to the cosmic battle. ‘Be strong’ translates a passive imperative (endynamousthe), implying the believer receives strength from an outside source. The power originates in the Lord—the risen Christ—and is dispensed by the Spirit, as Ephesians 3:16 shows. The ‘strength of his might’ (kratos) points to God’s sovereign, invincible nature. Spiritual fortitude is not self-generated; it is drawn from union with Christ, who is seated above all rule and authority. The believer’s role is to actively depend on this gift, aligning with the power that already overcame death. This redefines strength as receptivity to God’s enabling presence.

Practical Application
We often feel overwhelmed by life’s demands, temptations, and spiritual darkness. This verse invites us to stop trying harder in our own strength and to rest in God’s power. Begin each day acknowledging your limitations and asking the Holy Spirit to fill you with Christ’s might. When facing a difficult conversation, a persistent sin, or a moment of despair, pause and pray, ‘Lord, I cannot, but you can in me.’ Trust that his strength is made perfect in your weakness. This reliance turns daily battles into opportunities for God to display his sufficiency.
