Ephesians 6:15

“And your feet shod with the preparation of the Gospel of peace.] The Gospel is so called, because it makes men to be of peaceable tempers and behaviour, and gives peace to distressed minds: it directs the way to eternal peace, and publishes peace made by the blood of Christ; and has a much better claim to this name, and epithet, than the law has, which is often called “peace” by the Jews f82: the “preparation” of it does not design a promptitude or readiness to preach the Gospel, or to receive it, or profess it, or to give a reason of faith in it, or to endure reproach and persecution for it; nor that readiness which the Gospel is a means of, as for every good work, for the spiritual…”

“Translate, "Having shod your feet" (referring to the sandals, or to the military shoes then used). the preparation--rather, "the preparedness," or "readiness of," that is, arising from the "Gospel" (Psa 10:17).

“6:15 For shoes, put on the peace that comes from the Good News: In this context, the focus is on letting one’s life be governed by the peace that the Good News gives (see Rom 5:1).”
