The whole idea that halloween is to celebrate evil and worship it and all, is false. That's a man made idea, it's a very common misconception. Halloween, or Harvest as it was originally called, has a good purpose. It's to celebrate the end of summer, and beginning of fall/winter. The beautiful leaves falling all around, the trees changing colors, pumpkins, corn, etc. is for color. I personally love the colors of it all, it's amazing, like God's beauty all around us. His creations. My little niece and I, painted our faces, okay I did the painting, anyways....we had the rainbow colors for a reason. We were ''God's promise/covinent'' that was made with Noah. From the great flood. How God said He would never destroy the world again with a great flood and all. Also, we did it in a manner that we looked like warriors in a way, as we're God's warriors.Fighting for Him and His word. We had a blue cross in the middle of the forehead as a symbol of how we live for Jesus. Red comming down from our eyes like tears, from Jesus' blood having to be shed. So many differnet things, and with meaning. I'm not going all out, I don't see the point in it. However we did that, and carved a pumpkin, to celebrate harvest, from summer to fall and winter. Quality time to be cherished that was spent with my only niece, the angel God used to touch and change me so much.
I say, so long as you aren't celebrating or worshipping the dead, or false gods, etc. you're fine. No evil is intended, so it's not an issue. There's so many man made things in the world it's crazy. Allow God to speak to each one, and if they feel convicted of something, then whatever happens. They and God can deal with it, other wise, if they don't feel convicted of whatever they're doing, then I suppose God's okay with it eh. Ah well, just my thoughts.
