Make a candy corn pattern on cardstock paper. Write a Bible verse on the back. Let the children color the front of the candy corn using yellow and orange highlighters. When they are finished coloring, add the words "You picked a treat from my bowl, now here's a treat for your soul." Punch a hole in the top of the paper candy corn and tie on a small bag of real candy corn. Let the children hand these out to trick-or-treaters.
Read the story "The Pumpkin Patch Parable" by Liz Curtis Higgs to your children. Explain to them that God takes out the yucky sin from our lives and replaces it with His light and joy in the same way that the farmer in the story does to the pumpkin. Have the children help you scoop the insides out of a pumpkin. Let them draw on the face with markers. After they have scooted a safe distance away from you, use a knife to carve the face that they have drawn. You can also let them decorate small pumpkins with paint, markers, yarn and googly eyes.
Explain to your children that farmers use scarecrows to scare away the birds that want to eat their crops. The scarecrows protect the farmer's crops. In the same way, God has promised to protect us and never leave us. Have your children make scarecrow lollipops by wrapping the top of the lollipops with a piece of burlap and secure it with a string. Let the children draw on faces and make a hat for it out of felt.
Talk to your children about how Jesus lives in us and His light can shine out of us. Give them each a baby food jar and have them cover it with orange squares of tissue paper. For glue, give them watered down school glue and add a little glitter for fun. This will make a nice votive holder when it is dry. If you would like to give the pumpkin a face, cut out small triangles and smiles from black paper and stick them on the votive holder while it is still wet.
