Maybe “put on the armor of God” means put on the same armor God himself uses. That makes the Ephesians passage carry a lot more gravity, or so it seems to me.
“He put on righteousness as a breastplate, and a helmet of salvation on his head; he put on garments of vengeance for clothing, and wrapped himself in zeal as a cloak.”
Isaiah 59:17 ESV
“Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm. Stand therefore, having fastened on the belt of truth, and having put on the breastplate of righteousness, and take the helmet of salvation, and the sword of the Spirit, which is the word of God,”
Ephesians 6:13-14, 17 ESV
