When Paul describes the armor of God in Ephesians 6, he begins with the belt of truth—a piece of equipment that might seem small, but was absolutely essential for a soldier. Without it, the rest of the armor could not be held together, and the soldier would be left vulnerable and unprepared. In the same way, truth is the foundation of our spiritual defense. The battlefield of this unseen war is not fought with swords or shields, but in our minds, where lies and deceptions threaten to distort our identity and shake our faith. Satan whispers doubts—about God’s goodness, about our worth, about who we are—but the truth of God’s Word secures us, steadies us, and sets us free. To “gird ourselves with truth” is to be ready for battle, anchored in what God has said, so we can stand firm when the enemy attacks.
