. This exhortation is the most vivid portrayal of the Christian spiritual struggle, in a metaphor of warfare, with detailed list of equipment of the Divine Warrior.
Verse 10 :
Finally, my brethren, be strong in the Lord, and in the power of his might. • "Be strong": the Greek word here is in present tense, not aorist, suggesting the 'maintenance' rather than the 'attainment' of strength, whereas the Latin versions read
confortamini, recalling the original idea of "comfort", "comforter,” in older English usage.
Verse 11 :
Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. • Compare the various elements of the whole armour of God here to
Wisdom 5:17–20 ("The Lord will take his zeal as his whole armour, and will arm all creation to repel his enemies").
Verse 12 :
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. Verse 13 :
Therefore take up the whole armour of God, that you may be able to withstand in the evil day, and having done all, to stand. • "Take up the whole armour of God": a repetition of the exhortation in Ephesians 6:11, which seems necessary due to many powerful enemies as mentioned in the previous verse, to be followed by an account of the several parts of this armour. ==Conclusion and Benediction (6:21-24)==
