When the Philistine champion Goliath terrified the Israelite army with his size and threats, David volunteered to fight him despite being just a boy. David rejected King Saul’s armor, choosing instead to face the giant with five smooth stones and his sling, declaring he came in the name of the Lord. He struck Goliath in the forehead with a stone, winning a great victory for Israel and proving that God is greater than any scary situation we face.
