Picture the scene of David and Goliath in your mind. Does it look a lot like this cartoon? Many slight the story as just a little brave guy getting lucky with a sling, against a big bad guy. The end. Consider David was an expert slinger. David slew Goliath, because God guided the rock. Do you think God may have intervened, and added a tremendous velocity to the rock? The rock sunk inside the brain. YHVH was in the midst. This is not an event of little guy against big giant, where God uses foolish to confound the wise. This is an event of - FAITH.
