It's good, not evil, for Christian kids to have an alternative and for Halloween to be used a community outreach to the lost.
It's more dangerous to deny kids a fun day at this time of the year, make them feel like they are missing out and, potentially, drive them away from God.
Popping popcorn, baking pumpkin casserole, dipping caramel apples,or making apple pie, getting the fun movie lineup. Would love to be on a FR Happy Halloween thread should one pop up. It is what is in the heart that matters when you do anything. I intend on having a very Happy Halloween.
