The stories of the Bible I loved the most as a kid were the ones where God did something unimaginable- walking on water, healing people, coming back from the dead. My favorite ones told how somebody like me could do something amazing. The best was David and Goliath.
I can remember making a sling and trying to learn to throw rocks right where I wanted. I tried and I tried, but I never quite got the hang of it. In my child's mind, I thought if I worked hard enough I could do it too. My inner child forgot that God was with David, and I was just having fun.
The five smooth stones are not special. They were normal stones from a stream. The David and Goliath story is amazing because God used small things (5 stones and a young man) to take down a big giant.
God can take out your giants too!
