My mom had a big devil. She was always worried about him and always resisting him. People that believe in a big devil often spend lots of time talking about him. They are wasting time that could be directed toward our loving heavenly Father. For more on this topic see:

Anyway, all of this went out the window on Halloween. My mom loved Halloween! She would put on scary music, turn the lights down and wait for the kids. She had a sign with a witch on it that she put on the front door every year that read, "Welcome kiddies, put all your goodies in the box below. Go quietly and no one will get hurt."
I just want to weigh in on Halloween. It is not the devil's day. The devil does not get a day. he is a created being. he is not the opposite of God. he can't be everywhere at the same time any more than Gabriel or Michael, the other archangels. I am not even capitalizing the word he when I refer to him at the beginning of a sentence.
We should spend our days loving God, not fighting the devil.
Halloween is a great day for kids. Love them. Dress them up. Feed them candy. It makes for great memories.
It's a beautiful day in God's world, be sure to see the good.
