Finding true spiritual courage isn't about inner strength but trusting in God's presence and promises, as demonstrated by Polycarp and Joshua. God assures us we're not alone because He is with us, not powerless because He commands courage, and not directionless because He has spoken through Scripture. This courage enables us to face challenges not through willpower but through Scripture-saturated obedience. When feeling anxious or uncertain, we can remember God's presence as the antidote to fear, recognizing courage as a spiritual discipline rooted in knowing God rather than a personality trait.
