1 Samuel 17:58

And Saul said to him, Whose son art thou, thou young man? And David answered, I am the son of thy servant Jesse, the Bethlehemite. With this information Saul could now carry out his promise of which the soldiers had spoken. David's battle with Goliath is a picture of the battle which is the lot of all Christians in overcoming the attacks of Satan and of the sneering unbelievers. Although the odds often seem decidedly unfavorable to the Christians, they always have the Lord of hosts on their side and therefore must finally obtain the victory. At the same time we are here reminded of the great Son of David, who also, in a most singular manner, conquered the prince of this world and has given us the victory.
