Passage
Finally, brethren, be strengthened in the Lord and in the might of his power.
Finally, brethren, be strengthened in the Lord and in the might of his power.
Ephesians 6:8 Knowing that whatsoever good thing any man shall do, the same shall he receive from the Lord, whether he be bond or free.
Ephesians 6:9 And you, masters, do the same things to them, forbearing threatenings: knowing that the Lord both of them and you is in heaven. And there is no respect of persons with him.
Ephesians 6:10 Finally, brethren, be strengthened in the Lord and in the might of his power.
Ephesians 6:11 Put you on the armour of God, that you may be able to stand against the deceits of the devil.
Ephesians 6:12 For our wrestling is not against flesh and blood; but against principalities and powers, against the rulers of the world of this darkness, against the spirits of wickedness in the high places.
The verse centers on "finally", "brethren", "strengthened", "lord", "might", and "power". It is saying that the verse draws attention to "finally" and "brethren", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "And you masters do the same things..." into verse 11's "Put you on the armour of God...", so "finally" and "brethren" 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 "brethren" with trust shaped by these words, not by a vague optimism outside the passage.
