When the young peach-skinned David made his way across the Valley of Elah that morning to confront the crude, bellicose Philistine giant Goliath, he looked every bit like a lamb on its way to slaughter. Not a single soldier in all the army of Israel, not Saul, not any of his commanders, not any of his most experienced, most well equipped warriors had risen to the occasion, not one. The only taker was a young shepherd boy, armed with only his shepherd’s staff, pouch and sling, and an indomitable faith in the living LORD God Almighty. What happened that day made holy history, and stands as the quintessential example of the formidable giants we can sometimes face and the conquering faith that can easily slay them, as we’ll see this morning in 1 Samuel 17:1-51, in a message entitled, “Defeating the Undefeatable”.
