Eph 6:15

6:15 shoes for your feet. Despite a clear allusion to Is. 52:7, Paul does not have in mind the barefooted messenger who takes the gospel to others. The image here is of the Roman soldier’s sturdy sandals, which gave him stability and protection in battle. Ironically, the peace that comes from the gospel readies one for war against evil (2:14, 15, 17).
