As the shepherd-turned-warrior reached into the brook that day–only moments away from engaging in what would become the legendary battle of a lifetime–he did something that has been the object of much speculation and conjecture down through the preceding centuries: he drew out 5 smooth stones. The question is: why 5? While Scripture is silent as to David’s exact reason(s), many believe that Goliath also had 4 brothers. Perhaps David intended to make it a 5-for-1 deal that day should they have decided to intervene?
Personally, I like to think of that 5-fold collection of stones as representing an infinitely greater and more powerful force—J-E-S-U-S. With the Lord by David’s side that day, he couldn’t miss because the power wasn’t in the stone at all—it was in the ROCK who was guiding it. Consequently, it was that same spiritual ROCK who, many years later, entered into a far greater battle of eternal significance and, in similar fashion, bruised the head of Satan in defeat—abolishing forever the gargantuan power of sin and death on behalf of all who trust in Him. Romans 8:3 says it like this: For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh.
Strength and Honor.
