Matthew Poole and continuators on Ephesians 6:15

15. And your feet shod with the preparation of the gospel of peace .

In allusion to the Greaves or military shoes with which Souldiers covered their feet and legs. A Christian's way lies through rough places, through Briars and Thorns, and therefore he needs this piece of armour. He must be prepared to hold the Faith, and confess Christ in the most difficult times.

With that furniture which the Gospel affords him, which being a Gospel of peace, and bringing the glad tidings of Reconciliation to God by Christ, prepares Men best to undergo the troubles of the World. Ioh. 16.33.
