Passage
Put you on the armour of God, that you may be able to stand against the deceits of the devil.
Put you on the armour of God, that you may be able to stand against the deceits of the devil.
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.
Ephesians 6:13 Therefore, take unto you the armour of God, that you may be able to resist in the evil day and to stand in all things perfect.
The verse centers on "armour", "able", "stand", "against", "deceits", and "devil". It is saying that the verse draws attention to "armour" and "able", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "Finally brethren be strengthened in the Lord..." into verse 12's "For our wrestling is not against flesh...", so "armour" and "able" 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 "armour" and "able" with trust shaped by these words, not by a vague optimism outside the passage.
