What does 1 Samuel 17:44 Mean?

Context Summary

David did not wait until his enemy had crossed the valley, but hastened to the streamlet to select the pebbles needed for his sling. Goliath scouted such a champion and cursed him. To this boasting and blaspheming, David opposed the name of Jehovah of Hosts-the unseen hosts of heaven, the twelve legions of angels, of which our Lord spoke. That God-the God of Israel-would assuredly take up the challenge, and vindicate His servant's faith. Thus all Gentile nations would see that the God of Israel was a living reality, while Israel also would learn the too-long-forgotten lesson that Jehovah saveth not by sword nor spear.

So confident was the Philistine that he did not trouble to draw his sword nor let down the visor of his helmet. One thrust of his heavy spear, he reckoned, was all that would be required. But in a moment more Goliath was lying helpless on the ground. It is thus that God's champions, in every age, have gone out against giant wrongs, as Luther against Tetzel, or Garrison against slavery; and it is thus that we may confidently over-throw the inbred sins that claim supremacy over our lives.
