Passage
Finally, my brethren, be strong in the Lord, and in the power of his might.
Finally, my brethren, be strong in the Lord, and in the power of his might.
Ephesians 6:8 And knowe ye that whatsoeuer good thing any man doeth, that same shall he receiue of the Lord, whether he be bond or free.
Ephesians 6:9 And ye masters, doe the same things vnto them, putting away threatning: and know that euen your master also is in heauen, neither is there respect of person with him.
Ephesians 6:10 Finally, my brethren, be strong in the Lord, and in the power of his might.
Ephesians 6:11 Put on the whole armour of God, that ye may be able to stand against the assaultes of the deuil.
Ephesians 6:12 For we wrestle not against flesh and blood, but against principalities, against powers, and against the worldly gouernours, the princes of the darkenesse of this worlde, against spirituall wickednesses, which are in ye hie places.
The verse centers on "finally", "brethren", "strong", "lord", "power", and "might". 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 ye masters doe the same things..." into verse 11's "Put on the whole 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.
