THE SHIELD OF FAITH
Ken Fleeman
In Ephesians 6, amidst the call to put on the whole armor of God, Paul introduces the "shield of faith" (v. 16). To understand the power of this imagery, we must look to the ancient Roman world that inspired Paul's writing.
Hollywood usually depicts the round, decorative shield of the elite soldier but it is entirely possible that Paul had the Roman scutum in mind. This was not a small, decorative shield. It was a massive, rectangular, curved plank of layered wood, reinforced with metal, designed to provide comprehensive coverage. This "door-like" shield was the Roman foot soldier's mobile fortress in New Testament times. In standard formation, soldiers would advance side-by-side, interlocking their scuta to form an impenetrable wall. They could push forward as a single, protected unit. A similar formation known as the testudo (tortoise) allowed them to withstand volleys of arrows, spears, and large missiles, When facing a barrage, a soldier didn't just passively hold the scutum; he aggressively planted it, creating a fortified position. Others held their scutum overhead providing complete protection. The scutum’s design emphasizes protection and advancing position rather than just deflecting individual blows.
Paul specifies the purpose of this spiritual shield: "wherewith ye shall be able to quench all the fiery darts of the wicked." These aren't just arrows; they are fiery darts. In ancient warfare, this meant missiles wrapped in flammable pitch. They were designed to cause massive damage and spread panic. These fiery darts represent the raging barrage of assaults from the adversary—accusations, sudden temptations, irrational fears, doubts about God’s promises, and the stinging wounds of discouragement. These attacks don't just graze; they burn. They rain down on us constantly, aiming to destroy our hope and our peace.
The shield of faith is not a passive mental state or a vague feeling. It is the active application of our trust in God’s character and promises. When the dart of accusation flies (“You have failed, God cannot love you”), faith doesn’t just ignore it. Faith lifts the shield of God’s promise: "There is therefore now no condemnation to them which are in Christ Jesus" (Romans 8:1). When the dart of fear strikes (“Your situation is hopeless”), faith lifts the shield: "God is our refuge and strength, a very present help in trouble" (Psalm 46:1).
Wielding this shield means choosing to believe what God says is true over the intense internal or external pressure to believe otherwise. It’s an intellectual, emotional, and spiritual commitment. It requires us to “fix our eyes on Jesus” (Hebrews 12:2) rather than the burning arrows falling on and around us. When doubt flares, faith pushes back with the steadfastness of God's unchanging nature.
Paul also includes an essential command: "Above all, taking the shield of faith..." The word "taking" signifies the active, deliberate effort required. A soldier did not casually have his shield strapped to him “just in case”. It was essential. He had to lift its considerable weight, position it correctly, and hold it steady. Similarly, faith is not a passive inheritance from your parents or grandparents; it must be your own and it must be exercised. Pick up your shield. Know God. Speak with God. Trust God. Your life depends on it. We must be willing to endure the fatigue of constant spiritual resistance, drawing strength from the knowledge that God Himself is our "sun and shield" (Psalm 84:11).
The shield of faith is our primary defensive tool, but as Paul implies, it must be combined with the shields of other believers. The power of the testudo formation was in its unity. Our faith is strengthened when we support each other in our spiritual family. Together, lifting our shields of faith and trusting in the impenetrable armor of God, we find the strength not only to withstand the "evil day" but to quench every fiery dart and stand firm in victory with Christ.
