What does it actually mean to walk by faith and not by sight? That question sits at the heart of this message, and it cuts deeper than we might expect. Drawing from Ephesians 6, we explore the fourth piece of the armor of God: the shield of faith. Just as the Roman soldier carried a large shield called a scutum, designed to deflect flaming arrows and even link together with fellow soldiers to form an impenetrable wall, we are called to take up faith as an active, deliberate defense against the relentless attacks of the enemy. The imagery is striking and deeply practical. Faith is not passive. It is something we pick up, hold out, and use in the heat of the moment. And perhaps most powerfully, it is something we hold together. The shield wall reminds us that faith was never meant to be a solo endeavor. When our own faith wavers, the body of Christ is meant to surround us and hold the line. This message challenges us to ask honestly: where is our allegiance truly placed? Because where our allegiance goes, our faith will follow.
