Ephesians 6:15 - Exposition

And having shod your feet with the preparation of the gospel of peace. The metaphor becomes somewhat difficult to follow; the feet have to be shod or armed as with military sandals, and the sandal is the ἑτοιμασία , or preparedness of, or caused by, the gospel of peace. The idea seems to be that the mind is to be steadied, kept from fear and flutter, by means of the good news of peace—the good news that we are at peace with God; and "if God be for us, who can be against us?" The Roman sandal was furnished with nails that gripped the ground firmly, even when it was sloping or slippery; so the good news of peace keeps us upright and firm.
