And the Philistine moved forward and came near to David, with his shield-bearer in front of him. And when the Philistine looked and saw David, he disdained him, for he was but a youth, ruddy and handsome in appearance. And the Philistine said to David, “Am I a dog, that you come to me with sticks?” And the Philistine cursed David by his gods. The Philistine said to David, “Come to me, and I will give your flesh to the birds of the air and to the beasts of the field.” Then David said to the Philistine, “You come to me with a sword and with a spear and with a javelin, but I come to you in the name of the Lord of hosts, the God of the armies of Israel, whom you have defied. This day the Lord will deliver you into my hand, and I will strike you down and cut off your head. And I will give the dead bodies of the host of the Philistines this day to the birds of the air and to the wild beasts of the earth, that all the earth may know that there is a God in Israel, and that all this assembly may know that the Lord saves not with sword and spear. For the battle is the Lord‘s, and he will give you into our hand.” 1 Samuel 17:41-47.
David went up against Goliath with a sling and a stone, but also with much more than that. He came with boldness, and confidence that God was with him. He had taken on challenges before while protecting his father’s sheep. And he credited God with killing the bear and the lion. And now his zeal for God’s honor propelled him forward.
This is a rare thing; not that God will deliver us, but the boldness and eagerness to honor God’s name. We are all heirs of God’s covenant, and our faith in Christ comes with spiritual weapons that are able to invade the physical world. But we must dare to speak it and do it, even though the rest of the congregation trembles.
