Like Greek and Roman armor, the Shield of Faith offers both defensive protection and offensive agility. Biblical faith is active, not passive, marked by 27 verbs in Hebrews 11. We "obtain" a testimony through the struggle of faith but "receive" salvation as God's reward. Safeguarding virtues like peace and truth, this God-given faith is the victory that overcomes the world.

Just as Roman soldiers relied on the caliga (hobnailed sandal) for stability, protection, and endurance, Christians are to wear the "shoes of the gospel of peace" (Eph 6:15). This peace is not just the absence of conflict, but the shalom (wholeness) that comes from being justified by faith (Rom 5:1). This peace with God is our spiritual "hobnail," giving us a firm foundation to stand in chaos and the readiness to carry the good news of salvation (Is 52:7).

The breastplate protects the body's vital organs (heart, lungs, liver, kidneys, gut)—which mirror the five-fold ministry roles (Eph 4:11–13). Since humans are unrighteous , this physical protection symbolizes the need for the Breastplate of Righteousness to sustain the Army of God. Because our righteousness is flawed , we receive imputed righteousness through faith in Jesus Christ , whose perfect obedience acts as an eternal "transplant" for our spiritual life.

What is the relationship between a belt and truth? Does the history of the belt have anything to do with it?
