When I was a kid on Halloween, I was disappointed by the people who gave out fruit instead of candy. At least this woman wasn't on my trick-or-treat route:
Did you ever wonder why Halloween seems to primarily feed off of a market of 3-13 year olds? This is a Satanic ploy for our children. I don't think that Christian children should completely abstain from the festivities of costumes and candy, because they can be a light through their alternative behavior. [I personally plan on dressing my children up in Biblical and God-honoring characters that will draw people to ask questions.]
I'm talking to those of you who will be opening up your door to children of whom you do not know the state of their soul. Consider the gift that you offer them at your doorstep.
Consider your options. There are many message-driven alternatives to offer, other than a bowl full of candy. For instance, there are Gospel tracts designed for trick-or-treaters that can be purchased online or at your Christian bookstore. You might also want to consider designing your own tracts or attaching scripture messages to the treats.
