Child's interpretation of a rainbow

Preston saw a rainbow for the first time the other day and Im pretty sure that many rainbows have been in the sky during his life but since he can now name colors it was easier to point it out to him. I told him that it was sent from God to make us happy. He immediately said mommy you have to close your eyes, hold hands, and then we have to eat. He has associated the name God with eating because at mammys house we say the God is great, God is good let us thank him for our food prayer and then we eat. I informed him that we just ate and he informed me that God made the rainbow and now we have to eat. He settled on a popsicle instead. God made popsicles too!
