Recharged batteries

Micah has a recent fascination with batteries. Well, I should say the power that batteries provide, such as for his remote control cars and various other toys and things. Tonight while Scotty was praying he asked God to "recharge our batteries" tonight for the next day tomorrow. Micah interjected with a question, but Scotty told him to wait until he had finished praying. Shortly after the "Amen" Micah just had to get is question answered. The poor kid was confused and declared, "Why do we need recharged batteries?! We don't need to be charged!!"
