1 Samuel 17:40
40 And he took his staff in his hand, and chose him five smooth stones out of the brook, and put them in a shepherd’s bag which he had, even in a scrip; and his sling was in his hand: and he drew near to the Philistine.
-Why did David choose five stones when there was only one giant? The most obvious answer involves numerology. In the Bible, 5 is the number of grace and it’s only by God’s grace that we can overcome the Goliaths in our life. But there is another lesson being taught here that is equally important. The Holy Spirit is teaching us that no matter how big of a challenge we may be facing on a given day, there will always be more obstacles and more battles down the road. David chose five stones; after he beat David he had four left. David understood that there would be more “Goliaths” in his life. But just as with the first stone, he also understood that God would be with him on the day he needed to use the next one.
