Passage
Finally, be strong in the Lord, and in the strength of his might.
Finally, be strong in the Lord, and in the strength of his might.
Ephesians 6:8 knowing that whatever good thing each one does, he will receive the same again from the Lord, whether he is bound or free.
Ephesians 6:9 You masters, do the same things to them, and give up threatening, knowing that he who is both their Master and yours is in heaven, and there is no partiality with him.
Ephesians 6:10 Finally, be strong in the Lord, and in the strength of his might.
Ephesians 6:11 Put on the whole armor of God, that you may be able to stand against the wiles of the devil.
Ephesians 6:12 For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places.
The verse centers on "finally", "strong", "lord", "strength", and "might". It is saying that the verse draws attention to "finally" and "strong", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "You masters do the same things to..." into verse 11's "Put on the whole armor of God...", so "finally" and "strong" belong inside that flow. In Ephesians context, the local focus is grace, union with Christ, the church, and new creation.
A plain takeaway is to answer the verse's own emphasis on "finally" and "strong" with trust shaped by these words, not by a vague optimism outside the passage.
