The shoes of the gospel are the third piece of the armor of God: and your feet shod with the preparation of the gospel of peace. The Roman soldier's sandals (caligae) were heavily nailed on the soles for traction; the saint's spiritual footing is the gospel of peace, securing him for sustained combat. Where the foot is steady, the body fights; where it slips, the body falls.
(Ephesians 6:15.) The third piece of the armor; the saint's sustained-combat footing in the gospel of peace.
Roman caligae were sturdy hobnailed sandals giving traction in mud, on hillsides, in pursuit. They were a marker of soldier-status (the emperor Caligula was nicknamed for them in his childhood).
Preparation in Eph 6:15 (Greek hetoimasia) is ‘readiness’ or ‘firm footing’. The gospel gives the saint readiness to stand and to move.
Ephesians 6:15 — "And your feet shod with the preparation of the gospel of peace."
Isaiah 52:7 — "How beautiful upon the mountains are the feet of him that bringeth good tidings, that publisheth peace."
Romans 10:15 — "How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things."
Psalm 18:33 — "He maketh my feet like hinds' feet, and setteth me upon my high places."
Modern Christianity often forgets the foot-piece of the armor; the saint who cannot stand cannot fight.
The "shoes of the gospel of peace" gets sentimentalized as comfortable walking shoes for Christian life. Paul's image is Roman military footwear — hobnailed, traction-built, ready for battle. The corruption is replacing combat-readiness with comfort.
Greek hetoimasia (readiness, firm footing) plus euangelion (gospel).
Greek hetoimasia — readiness, preparation; firm footing.
Greek euangelion — gospel, good news.
"Footing is the unglamorous foundation of every other movement."
"The shoes are on first."
"How beautiful are the feet of them that preach the gospel of peace."
