Noah's pet fish died. When my husband joked that we should eat his dead fish, Noah refused because he wanted his fish to go to heaven. So his Daddy asked, "Why? If we eat your fish, it won't go to heaven?" Noah answered, "Yes. It will stay in my tummy."
Then later that night, Noah led our bedtime prayer: "Dear Jesus... Is my fish already there? Please tell me when my fish is there in heaven na." I found it so adorable that he was so concerned about his fish going to heaven. :)
