Experience and power vs. Faith and determination

A champion named Goliath, from Gath, came out of the Philistine camp. He was over nine feet tall. He had a bronze helmet on his head and wore a coat of scale armor of bronze weighing five thousand shekels; on his legs he wore bronze greaves, and a bronze javelin was slung on his back. His spear shaft was like a weaver's rod, and its iron point weighed six hundred shekels. His shield bearer went ahead of him.

Goliath stood and shouted to the ranks of Israel, "Why do you come out and line up for battle? Am I not a Philistine, and are you not the servants of Saul? Choose a man and have him come down to me. If he is able to fight and kill me, we will become your subjects; but if I overcome him and kill him, you will become our subjects and serve us."

For forty days the Philistine came forward every morning and evening and took his stand.

David, the youngest son of an Ephrathite named Jesse, from Bethlehem in Judah was told he was not able to go out against this Philistine and fight him; you are only a boy, and he has been a fighting man from his youth. With his faith in God, David convinced them to allow him to fight Goliath. Because David was uncomfortable in battle dress, he took his staff in his hand, chose five smooth stones from the stream, put them in the pouch of his shepherd's bag and, with his sling in his hand, approached the Philistine, in the name of the LORD Almighty, the God of the armies of Israel, whom you have defied. The whole world will know there is a God in Israel. All those gathered here will know it is not by sword or spear that the LORD saves; for the battle is the LORD's, and he will give all of you into our hands.

Reaching into his bag and taking out a stone, David slung it and struck the Philistine on the forehead. The stone sank into his forehead, and he fell facedown on the ground.

David triumphed over the Philistine with a sling and a stone.

When the Philistines saw their hero was dead, they turned and ran.
